+ GNU GENERAL PUBLIC LICENSE
+ Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+ Preamble
+
+ The licenses for most software are designed to take away your
+freedom to share and change it. By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users. This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it. (Some other Free Software Foundation software is covered by
+the GNU Lesser General Public License instead.) You can apply it to
+your programs, too.
+
+ When we speak of free software, we are referring to freedom, not
+price. Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+ To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+ For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have. You must make sure that they, too, receive or can get the
+source code. And you must show them these terms so they know their
+rights.
+
+ We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+ Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software. If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+ Finally, any free program is threatened constantly by software
+patents. We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary. To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+ The precise terms and conditions for copying, distribution and
+modification follow.
+
+ GNU GENERAL PUBLIC LICENSE
+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+ 0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License. The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language. (Hereinafter, translation is included without limitation in
+the term "modification".) Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope. The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+ 1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+ 2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+ a) You must cause the modified files to carry prominent notices
+ stating that you changed the files and the date of any change.
+
+ b) You must cause any work that you distribute or publish, that in
+ whole or in part contains or is derived from the Program or any
+ part thereof, to be licensed as a whole at no charge to all third
+ parties under the terms of this License.
+
+ c) If the modified program normally reads commands interactively
+ when run, you must cause it, when started running for such
+ interactive use in the most ordinary way, to print or display an
+ announcement including an appropriate copyright notice and a
+ notice that there is no warranty (or else, saying that you provide
+ a warranty) and that users may redistribute the program under
+ these conditions, and telling the user how to view a copy of this
+ License. (Exception: if the Program itself is interactive but
+ does not normally print such an announcement, your work based on
+ the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole. If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works. But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+ 3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+ a) Accompany it with the complete corresponding machine-readable
+ source code, which must be distributed under the terms of Sections
+ 1 and 2 above on a medium customarily used for software interchange; or,
+
+ b) Accompany it with a written offer, valid for at least three
+ years, to give any third party, for a charge no more than your
+ cost of physically performing source distribution, a complete
+ machine-readable copy of the corresponding source code, to be
+ distributed under the terms of Sections 1 and 2 above on a medium
+ customarily used for software interchange; or,
+
+ c) Accompany it with the information you received as to the offer
+ to distribute corresponding source code. (This alternative is
+ allowed only for noncommercial distribution and only if you
+ received the program in object code or executable form with such
+ an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it. For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable. However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+ 4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License. Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+ 5. You are not required to accept this License, since you have not
+signed it. However, nothing else grants you permission to modify or
+distribute the Program or its derivative works. These actions are
+prohibited by law if you do not accept this License. Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+ 6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions. You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+ 7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License. If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all. For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices. Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+ 8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded. In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+ 9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time. Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number. If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation. If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+ 10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission. For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this. Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+ NO WARRANTY
+
+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+ END OF TERMS AND CONDITIONS
+
+ How to Apply These Terms to Your New Programs
+
+ If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+ To do so, attach the following notices to the program. It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+ <one line to give the program's name and a brief idea of what it does.>
+ Copyright (C) <year> <name of author>
+
+ This program is free software; you can redistribute it and/or modify
+ it under the terms of the GNU General Public License as published by
+ the Free Software Foundation; either version 2 of the License, or
+ (at your option) any later version.
+
+ This program is distributed in the hope that it will be useful,
+ but WITHOUT ANY WARRANTY; without even the implied warranty of
+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ GNU General Public License for more details.
+
+ You should have received a copy of the GNU General Public License along
+ with this program; if not, write to the Free Software Foundation, Inc.,
+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+ Gnomovision version 69, Copyright (C) year name of author
+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+ This is free software, and you are welcome to redistribute it
+ under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License. Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary. Here is a sample; alter the names:
+
+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+ `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+ <signature of Ty Coon>, 1 April 1989
+ Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs. If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library. If this is what you want to do, use the GNU Lesser General
+Public License instead of this License.

+
+ bnxt_en: Fix SRIOV on big-endian architecture.
+
+ The PF driver sets up a list of firmware commands from the VF driver that
+ needs to be forwarded to the PF for approval. This list is a 256-bit
+ bitmap. The code that sets up the bitmap falls apart on big-endian
+ architecture. __set_bit() does not work because it operates on long types
+ whereas the firmware interface is defined in u32 types, causing bits in
+ the wrong 32-bit word to be set.
+
+ Fix it by setting the proper bits on an array of u32.

+
+ bnxt_en: Fix netpoll handling.
+
+ To handle netpoll properly, the driver must only handle TX packets
+ during NAPI. Handling RX events cause warnings and errors in
+ netpoll mode. The ndo_poll_controller() method should call
+ napi_schedule() directly so that a NAPI weight of zero will be used
+ during netpoll mode.
+
+ The bnxt_en driver supports 2 ring modes: combined, and separate rx/tx.
+ In separate rx/tx mode, the ndo_poll_controller() method will only
+ process the tx rings. In combined mode, the rx and tx completion
+ entries are mixed in the completion ring and we need to drop the rx
+ entries and recycle the rx buffers.
+
+ Add a function bnxt_force_rx_discard() to handle this in netpoll mode
+ when we see rx entries in combined ring mode.

+ bnxt_en: Fix NULL pointer dereference in reopen failure path
+
+ Net device reset can fail when the h/w or f/w is in a bad state.
+ Subsequent netdevice open fails in bnxt_hwrm_stat_ctx_alloc().
+ The cleanup invokes bnxt_hwrm_resource_free() which inturn
+ calls bnxt_disable_int(). In this routine, the code segment
+
+ if (ring->fw_ring_id != INVALID_HW_RING_ID)
+ BNXT_CP_DB(cpr->cp_doorbell, cpr->cp_raw_cons);
+
+ results in NULL pointer dereference as cpr->cp_doorbell is not yet
+ initialized, and fw_ring_id is zero.
+
+ The fix is to initialize cpr fw_ring_id to INVALID_HW_RING_ID before
+ bnxt_init_chip() is invoked.

+ mqprio: Modify mqprio to pass user parameters via ndo_setup_tc.
+
+ The configurable priority to traffic class mapping and the user specified
+ queue ranges are used to configure the traffic class, overriding the
+ hardware defaults when the 'hw' option is set to 0. However, when the 'hw'
+ option is non-zero, the hardware QOS defaults are used.
+
+ This patch makes it so that we can pass the data the user provided to
+ ndo_setup_tc. This allows us to pull in the queue configuration if the
+ user requested it as well as any additional hardware offload type
+ requested by using a value other than 1 for the hw value.
+
+ Finally it also provides a means for the device driver to return the level
+ supported for the offload type via the qopt->hw value. Previously we were
+ just always assuming the value to be 1, in the future values beyond just 1
+ may be supported.

+ bnxt_en: Add a set of TX rings to support XDP.
+
+ Add logic for an extra set of TX rings for XDP. If enabled, this
+ set of TX rings equals the number of RX rings and shares the same
+ IRQ as the RX ring set. A new field bp->tx_nr_rings_xdp is added
+ to keep track of these TX XDP rings. Adjust all other relevant functions
+ to handle bp->tx_nr_rings_xdp.

+
+ bnxt_en: Add tx ring mapping logic.
+
+ To support XDP_TX, we need to add a set of dedicated TX rings, each
+ associated with the NAPI of an RX ring. To assign XDP rings and regular
+ rings in a flexible way, we add a bp->tx_ring_map[] array to do the
+ remapping. The netdev txq index is stored in the new field txq_index
+ so that we can retrieve the netdev txq when handling TX completions.
+ In this patch, before we introduce XDP_TX, the mapping is 1:1.
+
+ v2: Fixed a bug in bnxt_tx_int().

+ bnxt_en: Centralize logic to reserve rings.
+
+ Currently, bnxt_setup_tc() and bnxt_set_channels() have similar and
+ duplicated code to check and reserve rx and tx rings. Add a new
+ function bnxt_reserve_rings() to centralize the logic. This will
+ make it easier to add XDP_TX support which requires allocating a
+ new set of TX rings.
+
+ Also, the tx ring checking logic in bnxt_setup_msix() can be removed.

+
+ Minor refactoring of bnxt_rx_skb() so that it can easily be replaced by
+ a new function that handles packets in a single page. Also, use a
+ function pointer bp->rx_skb_func() to switch to a new function when
+ we add the new mode in the next patch.
+
+ Add a new field data_ptr that points to the packet data in the
+ bnxt_sw_rx_bd structure. The original data field is changed to void
+ pointer so that it can either hold the kmalloc'ed data or a page
+ pointer.
+
+ The last parameter of bnxt_rx_skb() which was the length parameter is
+ changed to include the payload offset of the packet in the upper 16 bit.
+ The offset is needed to support the rx page mode and is not used in
+ this existing function.
+
+ v3: Added a new data_ptr parameter to bp->rx_skb_func(). The caller
+ has the option to modify the starting address of the packet. This
+ will be needed when XDP with headroom support is added.

+ bnxt_en: Fix RTNL lock usage on bnxt_update_link().
+
+ bnxt_update_link() is called from multiple code paths. Most callers,
+ such as open, ethtool, already hold RTNL. Only the caller bnxt_sp_task()
+ does not. So it is a bug to take RTNL inside bnxt_update_link().
+
+ Fix it by removing the RTNL inside bnxt_update_link(). The function
+ now expects the caller to always hold RTNL.
+
+ In bnxt_sp_task(), call bnxt_rtnl_lock_sp() before calling
+ bnxt_update_link(). We also need to move the call to the end of
+ bnxt_sp_task() since it will be clearing the BNXT_STATE_IN_SP_TASK bit.

+ bnxt_en: Fix bnxt_reset() in the slow path task.
+
+ In bnxt_sp_task(), we set a bit BNXT_STATE_IN_SP_TASK so that bnxt_close()
+ will synchronize and wait for bnxt_sp_task() to finish. Some functions
+ in bnxt_sp_task() require us to clear BNXT_STATE_IN_SP_TASK and then
+ acquire rtnl_lock() to prevent race conditions.
+
+ There are some bugs related to this logic. This patch refactors the code
+ to have common bnxt_rtnl_lock_sp() and bnxt_rtnl_unlock_sp() to handle
+ the RTNL and the clearing/setting of the bit. Multiple functions will
+ need the same logic. We also need to move bnxt_reset() to the end of
+ bnxt_sp_task(). Functions that clear BNXT_STATE_IN_SP_TASK must be the
+ last functions to be called in bnxt_sp_task(). The common scheme will
+ handle the condition properly.

+
+ bnxt_en: Add interface to support RDMA driver.
+
+ Since the network driver and RDMA driver operate on the same PCI function,
+ we need to create an interface to allow the RDMA driver to share resources
+ with the network driver.
+
+ 1. Create a new bnxt_en_dev struct which will be returned by
+ bnxt_ulp_probe() upon success. After that, all calls from the RDMA driver
+ to bnxt_en will pass a pointer to this struct.
+
+ 2. This struct contains additional function pointers to register, request
+ msix, send fw messages, register for async events.
+
+ 3. If the RDMA driver wants to enable RDMA on the function, it needs to
+ call the function pointer bnxt_register_device(). A ulp_ops structure
+ is passed for RCU protected upcalls from bnxt_en to the RDMA driver.
+
+ 4. The RDMA driver can call firmware APIs using the bnxt_send_fw_msg()
+ function pointer.
+
+ 5. 1 stats context is reserved when the RDMA driver registers. MSIX
+ and completion rings are reserved when the RDMA driver calls
+ bnxt_request_msix() function pointer.
+
+ 6. When the RDMA driver calls bnxt_unregister_device(), all RDMA resources
+ will be cleaned up.
+
+ v2: Fixed 2 uninitialized variable warnings.

+ bnxt_en: Refactor the driver registration function with firmware.
+
+ The driver register function with firmware consists of passing version
+ information and registering for async events. To support the RDMA driver,
+ the async events that we need to register may change. Separate the
+ driver register function into 2 parts so that we can just update the
+ async events for the RDMA driver.

+

+ net: Update API for VF vlan protocol 802.1ad support
+
+ Introduce new rtnl UAPI that exposes a list of vlans per VF, giving
+ the ability for user-space application to specify it for the VF, as an
+ option to support 802.1ad.
+ We adjusted IP Link tool to support this option.
+
+ For future use cases, the new UAPI supports multiple vlans. For now we
+ limit the list size to a single vlan in kernel.
+ Add IFLA_VF_VLAN_LIST in addition to IFLA_VF_VLAN to keep backward
+ compatibility with older versions of IP Link tool.
+
+ Add a vlan protocol parameter to the ndo_set_vf_vlan callback.
+ We kept 802.1Q as the drivers' default vlan protocol.
+ Suitable ip link tool command examples:
+ Set vf vlan protocol 802.1ad:
+ ip link set eth0 vf 1 vlan 100 proto 802.1ad
+ Set vf to VST (802.1Q) mode:
+ ip link set eth0 vf 1 vlan 100 proto 802.1Q
+ Or by omitting the new parameter
+ ip link set eth0 vf 1 vlan 100

+ bnxt_en: Fix ethtool -l|-L inconsistent channel counts.
+
+ The existing code is inconsistent in reporting and accepting the combined

+ cannot be bigger than max rx or max tx.
+
+ For example, if max rx = 2 and max tx = 1, we report max supported
+ combined to be 2. But if the user tries to set combined to 2, it will
+ fail because 2 is bigger than max tx which is 1.

+ bnxt_en: Improve the delay logic for firmware response.
+
+ The current code has 2 problems:
+
+ 1. The maximum wait time is not long enough. It is about 60% of the
+ duration specified by the firmware. It is calling usleep_range(600, 800)
+ for every 1 msec we are supposed to wait.
+
+ 2. The granularity of the delay is too coarse. Many simple firmware
+ commands finish in 25 usec or less.
+
+ We fix these 2 issues by multiplying the original 1 msec loop counter by
+ 40 and calling usleep_range(25, 40) for each iteration.
+
+ There is also a second delay loop to wait for the last DMA word to
+ complete. This delay loop should be a very short 5 usec wait.
+
+ This change results in much faster bring-up/down time:
+
+ Before the patch:
+
+ time ip link set p4p1 up
+
+ real 0m0.120s
+ user 0m0.001s

+
+ bnxt_en: Add workaround to detect bad opaque in rx completion (part 1)
+
+ There is a rare hardware bug that can cause a bad opaque value in the RX
+ or TPA completion. When this happens, the hardware may have used the
+ same buffer twice for 2 rx packets. In addition, the driver will also
+ crash later using the bad opaque as the index into the ring.
+
+ The rx opaque value is predictable and is always monotonically increasing.
+ The workaround is to keep track of the expected next opaque value and
+ compare it with the one returned by hardware during RX and TPA start
+ completions. If they miscompare, we will not process any more RX and
+ TPA completions and exit NAPI. We will then schedule a workqueue to
+ reset the function.
+
+ This patch adds the logic to keep track of the next rx consumer index.

+
+ bnxt_en: Separate bnxt_{rx|tx}_ring_info structs from bnxt_napi struct.
+
+ Currently, an rx and a tx ring are always paired with a completion ring.
+ We want to restructure it so that it is possible to have a dedicated
+ completion ring for tx or rx only.
+
+ The bnxt hardware uses a completion ring for rx and tx events. The driver
+ has to process the completion ring entries sequentially for the rx and tx
+ events. Using a dedicated completion ring for rx only or tx only has these
+ benefits:
+
+ 1. A burst of rx packets can cause delay in processing tx events if the
+ completion ring is shared. If tx queue is stopped by BQL, this can cause
+ delay in re-starting the tx queue.
+
+ 2. A completion ring is sized according to the rx and tx ring size rounded
+ up to the nearest power of 2. When the completion ring is shared, it is
+ sized by adding the rx and tx ring sizes and then rounded to the next power
+ of 2, often with a lot of wasted space.
+
+ 3. Using dedicated completion ring, we can adjust the tx and rx coalescing
+ parameters independently for rx and tx.
+
+ The first step is to separate the rx and tx ring structures from the
+ bnxt_napi struct.
+
+ In this patch, an rx ring and a tx ring will point to the same bnxt_napi
+ struct to share the same completion ring. No change in ring assignment
+ and mapping yet.

+ Call bnxt_cfg_rx_mode() in bnxt_init_chip() to setup uc_list and
+ mc_list mac address filters. Before the patch, uc_list is not
+ setup again after chip reset (such as ethtool ring size change)
+ and macvlans don't work any more after that.
+
+ Modify bnxt_cfg_rx_mode() to return error codes appropriately so
+ that the init chip sequence can detect any failures.

+ bnxt_en: enforce proper storing of MAC address
+
+ For PF, the bp->pf.mac_addr always holds the permanent MAC
+ addr assigned by the HW. For VF, the bp->vf.mac_addr always
+ holds the administrator assigned VF MAC addr. The random
+ generated VF MAC addr should never get stored to bp->vf.mac_addr.
+ This way, when the VF wants to change the MAC address, we can tell
+ if the adminstrator has already set it and disallow the VF from
+ changing it.

+ v2: Fix compile error if CONFIG_BNXT_SRIOV is not set.

+
+ bnxt_en: Fixed incorrect implementation of ndo_set_mac_address
+
+ The existing ndo_set_mac_address only copies the new MAC addr
+ and didn't set the new MAC addr to the HW. The correct way is
+ to delete the existing default MAC filter from HW and add
+ the new one. Because of RFS filters are also dependent on the
+ default mac filter l2 context, the driver must go thru
+ close_nic() to delete the default MAC and RFS filters, then
+ open_nic() to set the default MAC address to HW.

+ net: provide generic busy polling to all NAPI drivers
+
+ NAPI drivers no longer need to observe a particular protocol
+ to benefit from busy polling (CONFIG_NET_RX_BUSY_POLL=y)
+
+ napi_hash_add() and napi_hash_del() are automatically called
+ from core networking stack, respectively from
+ netif_napi_add() and netif_napi_del()
+
+ This patch depends on free_netdev() and netif_napi_del() being
+ called from process context, which seems to be the norm.
+
+ Drivers might still prefer to call napi_hash_del() on their
+ own, since they might combine all the rcu grace periods into
+ a single one, knowing their NAPI structures lifetime, while
+ core networking stack has no idea of a possible combining.
+
+ Once this patch proves to not bring serious regressions,
+ we will cleanup drivers to either remove napi_hash_del()
+ or provide appropriate rcu grace periods combining.

+
+ bnxt_en: More robust SRIOV cleanup sequence.
+
+ Instead of always calling pci_sriov_disable() in remove_one(),
+ the driver should detect whether VFs are currently assigned
+ to the VMs. If the VFs are active in VMs, then it should not
+ disable SRIOV as it is catastrophic to the VMs. Instead,
+ it just leaves the VFs alone and continues to unload the PF.
+ The user can then cleanup the VMs even after the PF driver
+ has been unloaded.

+ - Constify an array of strings (suggested by Stephen Hemminger)
+ - Improve bnxt_vf_pciid() (suggested by Stephen Hemminger)
+ - Use PCI_VDEVICE() to populate pci_device_id table for more compact
+ source.
+
+ v3:
+ - Fixed 2 more sparse warnings.
+ - Removed some unused structures in .h files.
+
+ v2:
+ - Fixed all kbuild test robot reported warnings.
+ - Fixed many of the checkpatch.pl errors and warnings.

+Introduction
+============
+
+This file describes the bnxt_en Linux driver for the Broadcom NetXtreme-C
+and NetXtreme-E BCM573xx and BCM574xx 10/25/40/50 Gbps Ethernet Network
+Controllers and Broadcom Nitro BCM58700 4-port 1/2.5/10 Gbps Ethernet Network
+Controller.
+
+
+Limitations
+===========
+
+1. The current version of the driver will compile on RHEL7.x, RHEL6.x,
+OLE6.x UEK, SLES12, SLES11SP1 and newer, most 3.x/4.x kernels, and some
+2.6 kernels starting from 2.6.32.
+
+2. Laser needs to be brought up for Nitro BCM58700 Ethernet controller
+using the following command, to bring up the Link.
+
+ i2cset -f -y 1 0x70 0 7 && i2cset -f -y 1 0x24 0xff 0x0
+
+3. Each device supports hundreds of MSIX vectors. The driver will enable
+all MSIX vectors when it loads. On some systems running on some kernels,
+the system may run out of interrupt descriptors.
+
+
+Port Speeds
+===========
+
+On some dual-port devices, the port speed of each port must be compatible
+with the port speed of the other port. 10Gbps and 25Gbps are not compatible
+speeds. For example, if one port is set to 10Gbps and link is up, the other
+port cannot be set to 25Gbps. However, the driver will allow incompatible
+speeds to be set on the two ports if link is not up yet. Subsequent link up
+on one port will render the incompatible speed on the other port to become
+unsupported. A console message like this may appear when this scenario
+happens:
+
+ bnxt_en 0000:04:00.0 eth0: Link speed 25000 no longer supported
+
+If the link is up on one port, the driver will not allow the other port to
+be set to an incompatible speed. An attempt to do that will result in an
+error. For example, eth0 and eth1 are the 2 ports of the dual-port device,
+eth0 is set to 10Gbps and link is up.
+
+ ethtool -s eth1 speed 25000
+ Cannot set new settings: Invalid argument
+ not setting speed
+
+This operation will only be allowed when the link goes down on eth0 or if
+eth0 is brought down using ifconfig/ip.
+
+On some NPAR (NIC partioning) devices where one port is shared by multiple
+PCI functions, the port speed is pre-configured and cannot be changed by
+the driver.
+
+See Autoneg section below for additional information.
+
+
+BNXT_EN Driver Dependencies
+===========================
+
+The driver has no dependencies on user-space firmware packages as all necessary
+firmware must be programmed in NVRAM(or QSPI for Nitro BCM58700 devices).
+Starting with driver version 1.0.0, the goal is that the driver will be
+compatible with all future versions of production firmware. All future versions
+of the driver will be backwards compatible with firmware as far back as the
+first production firmware.
+
+The first production firmware is version 20.1.11 using Hardware Resource
+Manager (HWRM) spec. 1.0.0.
+
+ethtool -i displays the firmware versions. For example:
+
+ ethtool -i eth0
+
+will show among other things:
+
+ firmware-version: 20.1.11/1.0.0 pkg 20.02.00.03
+
+In this example, the first version number (20.1.11) is the firmware version,
+the second version number (1.0.0) is the HWRM spec. version. The third
+version number (20.02.00.03) is the package version of all the different
+firmware components in NVRAM. The package version may not be available on
+all devices.
+
+Using kernels older than 4.7, if CONFIG_VLAN_MODULE kernel option is set as a
+module option, the vxlan.ko module must be loaded before the bnxt_en.ko module.
+
+
+BNXT_EN Driver Settings
+=======================
+
+The bnxt_en driver settings can be queried and changed using ethtool. The
+latest ethtool can be downloaded from
+ftp://ftp.kernel.org/pub/software/network/ethtool if it is not already
+installed. The following are some common examples on how to use ethtool. See
+the ethtool man page for more information. ethtool settings do not persist
+across reboot or module reload. The ethtool commands can be put in a startup
+script such as /etc/rc.local to preserve the settings across a reboot. On
+Red Hat distributions, "ethtool -s" parameters can be specified in the
+ifcfg-ethx scripts using the ETHTOOL_OPTS keyword.
+
+Some ethtool examples:
+
+1. Show current speed, duplex, and link status:
+
+ ethtool eth0
+
+2. Set speed:
+
+Example: Set speed to 10Gbps with autoneg off:
+
+ ethtool -s eth0 speed 10000 autoneg off
+
+Example: Set speed to 25Gbps with autoneg off:
+
+ ethtool -s eth0 speed 25000 autoneg off
+
+On some NPAR (NIC partitioning) devices, the port speed and flow control
+settings cannot be changed by the driver.
+
+See Autoneg section below for additional information on configuring
+Autonegotiation.
+
+3. Show offload settings:
+
+ ethtool -k eth0
+
+4. Change offload settings:
+
+Example: Turn off TSO (TCP Segmentation Offload)
+
+ ethtool -K eth0 tso off
+
+Example: Turn off hardware GRO and LRO
+
+ ethtool -K eth0 gro off lro off
+
+Example: Turn on hardware GRO only
+
+ ethtool -K eth0 gro on lro off
+
+Note that if both gro and lro are set, the driver will use hardware GRO.
+
+5. Show ring sizes:
+
+ ethtool -g eth0
+
+6. Change ring sizes:
+
+ ethtool -G eth0 rx N
+
+Note that the RX Jumbo ring size is set automatically when needed and
+cannot be changed by the user.
+
+7. Get statistics:
+
+ ethtool -S eth0
+
+8. Show number of channels (rings):
+
+ ethtool -l eth0
+
+9. Set number of channels (rings):
+
+ ethtool -L eth0 rx N tx N combined 0
+
+ ethtool -L eth0 rx 0 tx 0 combined M
+
+Note that the driver can support either all combined or all rx/tx channels,
+but not a combination of combined and rx/tx channels. The default is
+combined channels to match the number of CPUs up to 8. Combined channels
+use less system resources but may have lower performance than rx/tx channels
+under very high traffic stress. rx and tx channels can have different numbers
+for rx and tx but must both be non-zero.
+
+10. Show interrupt coalescing settings:
+
+ ethtool -c eth0
+
+11. Set interrupt coalescing settings:
+
+ ethtool -C eth0 rx-frames N
+
+ Note that only these parameters are supported:
+ rx-usecs, rx-frames, rx-usecs-irq, rx-frames-irq,
+ tx-usecs, tx-frames, tx-usecs-irq, tx-frames-irq,
+ stats-block-usecs.
+
+12. Show RSS flow hash indirection table and RSS hash key:
+
+ ethtool -x eth0
+
+13. Run self test:
+
+ ethtool -t eth0
+
+ Note that only single function PFs can execute self tests. If a PF has
+ active VFs, only online tests can be executed.
+
+14. See ethtool man page for more options.
+
+
+Autoneg
+=======
+
+The bnxt_en driver supports Autonegotiation of speed and flow control on
+most devices. Some dual-port 25G devices do not support Autoneg. Autoneg
+must be enabled for 10GBase-T devices.
+
+Note that parallel detection is not supported when autonegotiating
+50GBase-CR2, 40GBase-CR4, 25GBase-CR, 10GbE SFP+. If one side is
+autonegoatiating and the other side is not, link will not come up.
+
+25G and 50G advertisements are newer standards first defined in the 4.7
+kernel's ethtool interface. To fully support these new advertisement speeds
+for autonegotiation, 4.7 (or newer) kernel and a newer ethtool utility are
+required.
+
+Below are some examples to illustrate the limitations when using 4.6 and
+older kernels:
+
+1. Enable Autoneg with all supported speeds advertised when the device
+currently has Autoneg disabled:
+
+ ethtool -s eth0 autoneg on advertise 0x0
+
+Note that to advertise all supported speeds (including 25G and 50G), the
+device must initially have Autoneg disabled. advertise is a hexadecimal
+value specifying one or more advertised speed. 0x0 is special value that
+means all supported speeds. See ethtool man page. These advertise values
+are supported by the driver:
+
+0x020 1000baseT Full
+0x1000 10000baseT Full
+0x1000000 40000baseCR4 Full
+
+2. Enable Autoneg with only 10G advertised:
+
+ ethtool -s eth0 autoneg on advertise 0x1000
+
+or:
+
+ ethtool -s eth0 autoneg on speed 10000 duplex full
+
+
+3. Enable Autoneg with only 40G advertised:
+
+ ethtool -s eth0 autoneg on advertise 0x01000000
+
+4. Enable Autoneg with 40G and 10G advertised:
+
+ ethtool -s eth0 autoneg on advertise 0x01001000
+
+Note that the "Supported link modes" and "Advertised link modes" will not
+show 25G and 50G even though they may be supported or advertised. For
+example, on a device that is supporting and advertising 10G, 25G, 40G, and
+50G, and linking up at 50G, ethtool will show the following:
+
+ ethtool eth0
+ Settings for eth0:
+ Supported ports: [ FIBRE ]
+ Supported link modes: 10000baseT/Full
+ 40000baseCR4/Full
+ Supported pause frame use: Symmetric Receive-only
+ Supports auto-negotiation: Yes
+ Advertised link modes: 10000baseT/Full
+ 40000baseCR4/Full
+ Advertised pause frame use: Symmetric
+ Advertised auto-negotiation: Yes
+ Speed: 50000Mb/s
+ Duplex: Full
+ Port: FIBRE
+ PHYAD: 1
+ Transceiver: internal
+ Auto-negotiation: on
+ Current message level: 0x00000000 (0)
+
+ Link detected: yes
+
+Using kernels 4.7 or newer and ethtool version 4.8 or newer, 25G and 50G
+advertisement speeds can be properly configured and displayed, without any
+of the limitations described above. ethtool version 4.8 has a bug that
+ignores the advertise parameter, so it is recommended to use ethtool 4.10.
+Example ethtool 4.10 output showing 10G/25G/40G/50G advertisement settings:
+
+ ethtool eth0
+ Settings for eth0:
+ Supported ports: [ FIBRE ]
+ Supported link modes: 10000baseT/Full
+ 40000baseCR4/Full
+ 25000baseCR/Full
+ 50000baseCR2/Full
+ Supported pause frame use: Symmetric Receive-only
+ Supports auto-negotiation: Yes
+ Advertised link modes: 10000baseT/Full
+ 40000baseCR4/Full
+ 25000baseCR/Full
+ 50000baseCR2/Full
+ Advertised pause frame use: No
+ Advertised auto-negotiation: Yes
+ Speed: 50000Mb/s
+ Duplex: Full
+ Port: Direct Attach Copper
+ PHYAD: 1
+ Transceiver: internal
+ Auto-negotiation: on
+ Supports Wake-on: d
+ Wake-on: d
+ Current message level: 0x00000000 (0)
+
+ Link detected: yes
+
+These are the complete advertise values supported by the driver using 4.7
+kernel or newer and a compatible version of ethtool supporting the new
+values:
+
+0x020 1000baseT Full
+0x1000 10000baseT Full
+0x1000000 40000baseCR4 Full
+0x80000000 25000baseCR Full
+0x400000000 50000baseCR2 Full
+
+Note that the driver does not make a distinction on the exact physical
+layer encoding and media type for a link speed. For example, at 50G, the
+device may support 50000baseCR2 and 50000baseSR2 for copper and multimode
+fiber cables respectively. Regardless of what cabling is used for 50G,
+the driver currently uses only the ethtool value defined for 50000baseCR2
+to cover all variants of the 50G media types. The same applies to all
+other advertise value for other link speeds listed above.
+
+
+Energy Efficient Ethernet
+=========================
+
+The driver supports Energy Efficient Ethernet (EEE) settings on 10GBase-T
+devices. If enabled, and connected to a link partner that advertises EEE,
+EEE will become active. EEE saves power by entering Low Power Idle (LPI)
+state when the transmitter is idle. The downside is increased latency as
+it takes a few microseconds to exit LPI to start transmitting again.
+
+On a 10GBase-T device that supports EEE, the link up console message will
+include the current state of EEE. For example:
+
+ bnxt_en 0000:05:00.0 eth0: NIC Link is Up, 10000 Mbps full duplex, Flow control: none
+ bnxt_en 0000:05:00.0 eth0: EEE is active
+
+The active state means that EEE is negotiated to be active during
+autonegotiation. Additional EEE parameters can be obtained using ethtool:
+
+ ethtool --show-eee eth0
+
+ EEE Settings for eth0:
+ EEE status: enabled - active
+ Tx LPI: 8 (us)
+ Supported EEE link modes: 10000baseT/Full
+ Advertised EEE link modes: 10000baseT/Full
+ Link partner advertised EEE link modes: 10000baseT/Full
+
+The tx LPI timer of 8 microseconds is currently fixed and cannot be adjusted.
+EEE is only supported on 10GBase-T. 1GBase-T does not currently support EEE.
+
+To disable EEE:
+
+ ethtool --set-eee eth0 eee off
+
+To enable EEE, but disable LPI:
+
+ ethtool --set-eee eth0 eee on tx-lpi off
+
+This setting will negotiate EEE with the link partner but the transmitter on
+eth0 will not enter LPI during idle. The link partner may independently
+choose to enter LPI when its transmitter is idle.
+
+
+Enabling Receive Side Scaling (RSS)
+===================================
+
+By default, the driver enables RSS by allocating receive rings to match the
+the number of CPUs (up to 8). Incoming packets are run through a 4-tuple
+or 2-tuple hash function for TCP/IP packets and IP packets respectively.
+Non fragmented UDP packets are run through a 4-tuple hash function on newer
+devices (2-tuple on older devices). See below for more information about
+4-tuple and 2-tuple and how to configure it.
+
+The computed hash value will determine the receive ring number for the
+packet. This way, RSS distributes packets to multiple receive rings while
+guaranteeing that all packets from the same flow will be steered to the same
+receive ring. The processing of each receive ring can be done in parallel
+by different CPUs to achieve higher performance. For example, irqbalance
+will distribute the MSIX vector of each RSS receive ring across CPUs.
+However, RSS does not guarantee even distribution or optimal distribution of
+packets.
+
+To disable RSS, set the number of receive channels (or combined channels) to 1:
+
+ ethtool -L eth0 rx 1 combined 0
+
+or
+
+ ethtool -L eth0 combined 1 rx 0 tx 0
+
+To re-enable RSS, set the number of receive channels or (combined channels) to
+a value higher than 1.
+
+The RSS hash can be configured for 4-tuple or 2-tuple for various flow types.
+4-tuple means that the source, destination IP addresses and layer 4 port
+numbers are included in the hash function. 2-tuple means that only the source
+and destination IP addresses are included. 4-tuple generally gives better
+results. Below are some examples on how to set and display the hash function.
+

+
+
+Enabling Accelerated Receive Flow Steering (RFS)
+================================================
+
+RSS distributes packets based on n-tuple hash to multiple receive rings.
+The destination receive ring of a packet flow is solely determined by the
+hash value. This receive ring may or may not be processed in the kernel by
+the CPU where the sockets application consuming the packet flow is running.
+
+Accelerated RFS will steer incoming packet flows to the ring whose MSI-X
+vector will interrupt the CPU running the sockets application consuming
+the packets. The benefit is higher cache locality of the packet data from
+the moment it is processed by the kernel until it is consumed by the
+application.
+
+Accelerated RFS requires n-tuple filters to be supported. On older
+devices, only Physical Functions (PFs, see SR-IOV below) support n-tuple
+filters. On the latest devices, n-tuple filters are supported and enabled
+by default on all functions. Use ethtool to disable n-tuple filters:
+
+ ethtool -K eth0 ntuple off
+
+To re-enable n-tuple filters:
+
+ ethtool -K eth0 ntuple on
+
+After n-tuple filters are enabled, Accelerated RFS will be automatically
+enabled when RFS is enabled. These are example steps to enable RFS on
+a device with 8 rx rings:
+
+echo 32768 > /proc/sys/net/core/rps_sock_flow_entries
+echo 2048 > /sys/class/net/eth0/queues/rx-0/rps_flow_cnt
+echo 2048 > /sys/class/net/eth0/queues/rx-1/rps_flow_cnt
+echo 2048 > /sys/class/net/eth0/queues/rx-2/rps_flow_cnt
+echo 2048 > /sys/class/net/eth0/queues/rx-3/rps_flow_cnt
+echo 2048 > /sys/class/net/eth0/queues/rx-4/rps_flow_cnt
+echo 2048 > /sys/class/net/eth0/queues/rx-5/rps_flow_cnt
+echo 2048 > /sys/class/net/eth0/queues/rx-6/rps_flow_cnt
+echo 2048 > /sys/class/net/eth0/queues/rx-7/rps_flow_cnt
+
+These steps will set the global flow table to have 32K entries and each
+receive ring to have 2K entries. These values can be adjusted based on
+usage.
+
+Note that for Accelerated RFS to be effective, the number of receive channels
+(or combined channels) should generally match the number of CPUs. Use
+ethtool -L to fine-tune the number of receive channels (or combined channels)
+if necessary. Accelerated RFS has precedence over RSS. If a packet matches an
+n-tuple filter rule, it will be steered to the RFS specified receive ring.
+If the packet does not match any n-tuple filter rule, it will be steered
+according to RSS hash.
+
+To display the active n-tuple filters setup for Accelerated RFS:
+
+ ethtool -n eth0
+
+IPv6, GRE and IP-inIP n-tuple filters are supported on 4.5 and newer kernels.
+
+
+Enabling Busy Poll Sockets
+==========================
+
+Using 3.11 and newer kernels (also backported to some major distributions),
+Busy Poll Sockets are supported by the bnxt_en driver if
+CONFIG_NET_RX_BUSY_POLL is enabled. Individual sockets can set the
+SO_BUSY_POLL option, or it can be enabled globally using sysctl:
+
+ sysctl -w net.core.busy_read=50
+
+This sets the time to busy read the device's receive ring to 50 usecs.
+For socket applications waiting for data to arrive, using this method
+can decrease latency by 2 or 3 usecs typically at the expense of
+higher CPU utilization. The value to use depends on the expected
+time the socket will wait for data to arrive. Use 50 usecs as a
+starting recommended value.
+
+In addition, the following sysctl parameter should also be set:
+
+ sysctl -w net.core.busy_poll=50
+
+This sets the time to busy poll for socket poll and select to 50 usecs.
+50 usecs is a recommended value for a small number of polling sockets.
+
+
+Enabling SR-IOV
+===============
+
+The Broadcom NetXtreme-C and NetXtreme-E devices support Single Root I/O
+Virtualization (SR-IOV) with Physical Functions (PFs) and Virtual Functions
+(VFs) sharing the Ethernet port. The same bnxt_en driver is used for both
+PFs and VFs under Linux.
+
+Only the PFs are automatically enabled. If a PF supports SR-IOV, lspci
+will show that it has the SR-IOV capability and the total number of VFs
+supported. To enable one or more VFs, write the desired number of VFs
+to the following sysfs file:
+
+ /sys/bus/pci/devices/<domain>:<bus>:<device>:<function>/sriov_numvfs
+
+For example, to enable 4 VFs on bus 82 device 0 function 0:
+
+ echo 4 > /sys/bus/pci/devices/0000:82:00.0/sriov_numvfs
+
+To disable the VFs, write 0 to the same sysfs file. Note that to change
+the number of VFs, 0 must first be written before writing the new number
+of VFs.
+
+On older 2.6 kernels that do not support the sysfs method to enable SR-IOV,
+the driver uses the module parameter "num_vfs" to enable the desired number
+of VFs. Note that this is a global parameter that applies to all PF
+devices in the system. For example, to enable 4 VFs on all supported PFs:
+
+ modprobe bnxt_en num_vfs=4
+
+The 4 VFs of each supported PF will be enabled when the PF is brought up.
+
+The VF and the PF operate almost identically under the same Linux driver
+but not all operations supported on the PF are supported on the VF.
+
+The resources needed by each VF are assigned by the PF based on how many
+VFs are requested to be enabled and the resources currently used by the PF.
+It is important to fully configure the PF first with all the desired features,
+such as number of RSS/TSS channels, jumbo MTU, etc, before enabling SR-IOV.
+After enabling SR-IOV, there may not be enough resources left to reconfigure
+the PF.
+
+The resources are evenly divided among the VFs. Enabling a large number of
+VFs will result in less resources (such as RSS/TSS channels) for each VF.
+
+Refer to other documentation on how to map a VF to a VM or a Linux Container.
+
+Some attributes of a VF can be set using iproute2 through the PF. SR-IOV
+must be enabled by setting the number of desired VFs before any attributes
+can be set. Some examples:
+
+1. Set VF MAC address:
+
+ ip link set <pf> vf <vf_index> mac <vf_mac>
+
+Example:
+
+ ip link set eth0 vf 0 mac 00:12:34:56:78:9a
+
+Note that if the VF MAC addres is not set as shown, a random MAC address will
+be used for the VF. If the VF MAC address is changed while the VF driver has
+already brought up the VF, it is necessary to bring down and up the VF before
+the new MAC address will take effect.
+
+2. Set VF link state:
+
+ ip link set <pf> vf <vf_index> state auto|enable|disable
+
+The default is "auto" which reflects the true link state. Setting the VF
+link to "enable" allows loopback traffic regardless of the true link state.
+
+Example:
+
+ ip link set eth0 vf 0 state enable
+
+3. Set VF default VLAN:
+
+ ip link set <pf> vf <vf_index> vlan <vlan id>
+
+Example:
+
+ ip link set eth0 vf 0 vlan 100
+
+4. Set VF MAC address spoof check:
+
+ ip link set <pf> vf <vf_index> spoofchk on|off
+
+Example:
+
+ ip link set eth0 vf 0 spoofchk on
+
+Note that spoofchk is only effective if a VF MAC address has been set as
+shown in #1 above.
+
+
+Virtual Ethernet Bridge (VEB)
+=============================
+
+The NetXtreme-C/E devices contain an internal hardware Virtual Ethernet
+Bridge (VEB) to bridge traffic between virtual ports enabled by SR-IOV.
+VEB is normally turned on by default. VEB can be switched to VEPA
+(Virtual Ethernet Port Aggregator) mode if an external VEPA switch is used
+to provide bridging between the virtual ports.
+
+Use the bridge command to switch between VEB/VEPA mode. Note that only
+the PF driver will accept the command for all virtual ports belonging to the
+same physical port. The bridge mode cannot be changed if there are multiple
+PFs sharing the same physical port (e.g. NPAR or Multi-Host).
+
+To set the bridge mode:
+
+ bridge link set dev <pf> hwmode {veb/vepa}
+
+To show the bridge mode:
+
+ bridge link show dev <pf>
+
+Example:
+
+ bridge link set dev eth0 hwmode vepa
+
+Note that older firmware does not support VEPA mode.
+
+
+Hardware QoS
+============
+
+The NetXtreme-C/E devices support hardware QoS. The hardware has multiple
+internal queues, each can be configured to support different QoS attributes,
+such as latency, bandwidth, lossy or lossless data delivery. These QoS
+attributes are specified in the IEEE Data Center Bridging (DCB) standard
+extensions to Ethernet. DCB parameters include Enhanced Transmission
+Selection (ETS) and Priority-based Flow Control (PFC). In a DCB network,
+all traffic will be classified into multiple Traffic Classes (TCs), each
+of which is assigned different DCB parameters.
+
+Typically, all traffic is VLAN tagged with a 3-bit priority in the VLAN
+tag. The VLAN priority is mapped to a TC. For example, a network with
+3 TCs may have the following priority to TC mapping:
+
+0:0,1:0,2:0,3:2,4:1,5:0,6:0,7:0
+
+This means that priorities 0,1,2,5,6,7 are mapped to TC0, priority 3 to TC2,
+and priority 4 to TC1. ETS allows bandwidth assigment for the TCs. For
+example, the ETS bandwidth assignment may be 40%, 50%, and 10% to TC0, TC1,
+and TC2 respectively. PFC provides link level flow control for each VLAN
+priority independently. For example, if PFC is enabled on VLAN priority 4,
+then only TC1 will be subject to flow control without affecting the other
+two TCs.
+
+Typically, DCB parameters are automatically configured using the DCB
+Capabilities Exchange protocol (DCBX). The bnxt_en driver currently
+supports the Linux lldpad DCBX agent. lldpad supports all versions of
+DCBX but the bnxt_en driver currently only supports the IEEE DCBX version.
+Typically, the DCBX enabled switch will convey the DCB parameters to lldpad
+which will then send the hardware QoS parameters to bnxt_en to configure
+the device. Refer to the lldpad(8) and lldptool(8) man pages for further
+information on how to setup the lldpad DCBX agent.
+
+To support hardware TCs, the proper Linux qdisc must be used to classify
+outgoing traffic into their proper hardware TCs. For example, the mqprio
+qdisc may be used. A simple example using mqprio qdisc is illustrated below.
+Refer to the tc-mqprio(8) man page for more information.
+
+ tc qdisc add dev eth0 root mqprio num_tc 3 map 0 0 0 2 1 0 0 0 hw 1
+
+The above command creates the mqprio qdisc with 3 hardware TCs. The priority
+to TC mapping is the same as the example at the beginning of the section.
+The bnxt_en driver will create 3 groups of tx rings, with each group mapping
+to an internal hardware TC.
+
+Once this is created, SKBs with different priorities will be mapped to the
+3 TCs according to the specified map above. Note that this SKB priority
+is only used to direct packets within the kernel stack to the proper hardware
+ring. If the outgoing packets are VLAN tagged, the SKB priority does not
+automatically map to the VLAN priority of the packet. The VLAN egress map
+has to be set up to have the proper VLAN priority for each packet.
+
+In the current example, if VLAN 100 is used for all traffic, the VLAN egress
+map can be set up like this:
+
+ ip link add link eth0 name eth0.100 type vlan id 100 \
+ egress 0:0 1:1 2:2 3:3 4:4 5:5 6:6 7:7
+
+This creates a one-to-one mapping of SKB priority to VLAN egress priority.
+In other words, SKB priority 0 maps VLAN priority 0, SKB priority 1 maps to
+VLAN priority 1, etc. This one-to-one mapping should generally be used.
+
+If each TC has more than one ring, TSS will be performed to select a tx ring
+within the TC.
+
+To display the current qdisc configuration:
+
+ tc qdisc show
+
+Example output:
+
+ qdisc mqprio 8010: dev eth0 root tc 3 map 0 0 0 2 1 0 0 0 0 0 0 0 0 0 0 0
+ queues:(0:3) (4:7) (8:11)
+
+The example above shows that bnxt_en has allocated 4 tx rings for each of the
+3 TCs. SKBs with priorities 0,1,2,5,6,7 will be transmitted using tx rings
+0 to 3 (TC0). SKBs with priority 4 will be transmitted using rings 4 to 7
+(TC1). SKBs with priority 3 will be transmitted using rings 8 to 11 (TC2).
+
+Next, SKB priorities have to be set for different applications so that the
+packets from the different applications will be mapped to the proper TCs.
+By default, the SKB priority is set to 0. There are multiple methods to set
+SKB priorities. net_prio cgroup is a convenient way to do this. Refer to the
+link below for more information:
+
+https://www.kernel.org/doc/Documentation/cgroup-v1/net_prio.txt
+
+As mentioned previously, the DCB attributes of each TC are normally configured
+by the DCBX agent in lldpad. It is also possible to set the DCB attributes
+manually in a simple network or for test purposes. The following example
+will manually set up eth0 with the example DCB local parameters mentioned at
+the beginning of the section.
+
+ lldpad -d
+ lldptool -T -i eth0 -V ETS-CFG tsa=0:ets,1:ets,2:ets \
+ up2tc=0:0,1:0,2:0,3:2,4:1,5:0,6:0,7:0 \
+ tcbw=40,50,10
+ lldptool -T -i eth0 -V PFC enabled=4
+
+Note that the ETS bandwidth distribution will only be evident when all
+traffic classes are transmitting and reaching the link capacity.
+
+See lldptool-ets(8) and lldptool-pfc(8) man pages for more information.
+
+On an NPAR device with multiple partitions sharing the same network port,
+DCBX cannot be run on more than one partition. In other words, the lldpad
+adminStatus can be set to rxtx on no more than one partition. The same is
+true for SRIOV virtual functions. DCBX cannot be run on the VFs.
+
+On these multi-function devices, the hardware TCs are generally shared
+between all the functions. The DCB parameters negotiated and setup on
+the main function (NPAR or PF function) will be the same on the other
+functions sharing the same port. Note that the standard lldptool will
+not be able to show the DCB parameters on the other functions which have
+adminStatus disabled.
+
+
+PTP Hardware Clock
+==================
+
+The NetXtreme-C/E devices support PTP Hardware Clock which provides hardware
+timestamps for PTP v2 packets. The Linux PTP project contains more
+information about this feature. A newer 4.x kernel and newer firmware
+(2.6.134 or newer) are required to use this feature. Only the first PF
+of the network port has access to the hardware PTP feature. Use ethtool -T
+to check if PTP Hardware Clock is supported.
+
+
+BNXT_EN Module Parameters
+=========================
+
+On newer 3.x/4.x kernels, the driver does not support any driver parameters.
+Please use standard tools (sysfs, ethtool, iproute2, etc) to configure the
+driver.
+
+The only exception is the "num_vfs" module parameter supported on older 2.6
+kernels to enable SR-IOV. Please see the SR-IOV section above.
+
+
+BNXT_EN Driver Defaults
+=======================
+
+Speed : 1G/2.5G/10G/25G/40G/50G depending on the board.

+
+
+Statistics
+==========
+
+The driver reports all major standard network counters to the stack. These
+counters are reported in /proc/net/dev or by other standard tools such as
+netstat -i.
+
+Note that the counters are updated every second by the firmware by
+default. To increase the frequency of these updates, ethtool -C can
+be used to increase the frequency to 0.25 seconds if necessary.
+
+More detailed statistics are reported by ethtool -S. Some of the counters
+reported by ethtool -S are for diagnostics purposes only. For example,
+the "rx_drops" counter reported by ethtool -S includes dropped packets
+that don't match the unicast and multicast filters in the hardware. A
+non-zero count is normal and does not generally reflect any error conditions.
+This counter should not be confused with the "RX-DRP" counter reported by
+netstat -i. The latter reflects dropped packets due to buffer overflow
+conditions.
+
+Another example is the "tpa_aborts" counter reported by ethtool -S. It
+counts the LRO (Large Receive Offload) aggregation aborts due to normal
+TCP conditions. A high tpa_aborts count is generally not an indication
+of any errors.
+
+The "rx_ovrsz_frames" counter reported by ethtool -S may count all
+packets bigger than 1518 bytes when using earlier versions of the firmware.
+Newer version of the firmware has reprogrammed the counter to count
+packets bigger than 9600 bytes.
+
+
+Unloading and Removing Driver
+=============================
+
+rmmod bnxt_en
+
+Note that if SR-IOV is enabled and there are active VFs running in VMs, the
+PF driver should never be unloaded. It can cause catastrophic failures such
+as kernel panics or reboots. The only time the PF driver can be unloaded
+with active VFs is when all the VFs and the PF are running in the same host
+kernel environment with one driver instance controlling the PF and all the
+VFs. Using Linux Containers is one such example where the PF driver can be
+unloaded to gracefully shutdown the PF and all the VFs.
+
+
+Updating Firmware for Broadcom NetXtreme-C and NetXtreme-E devices
+==================================================================
+
+Controller firmware may be updated using the Linux request_firmware interface
+in conjunction with the ethtool "flash device" interface.
+
+Using the ethtool utility, the controller's boot processor firmware may be
+updated by copying the 2 "boot code" firmware files to the local /lib/firmware/
+directory:
+
+ cp bc1_cm_a.bin bc2_cm_a.bin /lib/firmware
+
+and then issuing the following 2 ethtool commands (both are required):
+
+ ethtool -f <device> bc1_cm_a.bin 4
+
+ ethtool -f <device> bc2_cm_a.bin 18
+
+NVM packages (*.pkg files) containing controller firmware, microcode,
+pre-boot software and configuration data may be installed into a controller's
+NVRAM using the ethtool utility by first copying the .pkg file to the local
+/lib/firmware/ directory and then executing a single command:
+
+ ethtool -f <device> <filename.pkg>
+
+Note: do not specify the full path to the file on the ethtool -f command-line.
+
+Note: root privileges are required to successfully execute these commands.
+
+After "flashing" new firmware into the controller's NVRAM, a cold restart of
+the system is required for the new firmware to take effect. This requirement
+will be removed in future firmware and driver versions.
+
+Updating Firmware for Broadcom Nitro device
+===========================================
+
+Nitro controller firmware should be updated from Uboot prompt by following the
+below steps
+
+ sf probe
+ sf erase 0x50000 0x30000
+ tftpboot 0x85000000 <location>/chimp_xxx.bin
+ sf write 0x85000000 0x50000 <size in hex>

+DETAILS:
+
+FPGA version 3.1.27:
+
+ To program FPGA
+ 1. RDP to any of pb_sniffer[5-10]
+ 2. Map \\pb_file_srvr\drive_e to a drive.
+ 3. Change directory to <DRIVE>\ProDesign\<FPGA version>
+ 4. Run “prg_fpga.bat” <IP address of FPGA>
+
+Chimp FW version 0.0.18:
+ Locaton: ~/nseg/rels/bcm5734x/firmware/ChiMP_Firmware/0.0.18
+
+ To program Chimp FW to NVRAM:
+ 1.esx-dbg (Administrator/broadcom) has the dos USB key.
+ 2.Open your setup idrac and map the usb key (use Mozilla or Chrome)
+ 3.Boot to dos
+ 4.cd cdiag/0915/
+ 5.cdiag.exe -eng
+ 6.Enter the following command in cdiag and wait for completion
+ 1:> nvm upgrade –cfw ncfc0000.17
+ 7.Enter the following command to get fw version
+ 1:> nvm dir
+
+Kernel:
+ Standard kernel that comes with RHEL7.0 or above
+ (Development was done using 3.10.0-123.el7.x86_64)
+
+Driver:
+ nseg: ~/nseg/rels/bcm5734x/drivers/linux/0.006
+
+iproute2:
+ https://www.kernel.org/pub/linux/utils/net/iproute2/ OR
+ git://git.kernel.org/pub/scm/linux/kernel/git/shemminger/iproute2.git
+
+============================================================================
+Know Issues/Limitations:
+
+SRIOV:
+ 1. Max 2 VF's can be enabled.
+ 2. All VF development/testing was done using 'network namespace' on the
+ hypervisor itself, no major issues are expected when VF driver is
+ brought up on a real VM.
+
+ a. To enable 'x' VF's
+ #echo x > /sys/bus/pci/devices/<pci_bus_id of PF0>/sriov_numvfs
+
+ b. To disable VF's
+ #echo 0 > /sys/bus/pci/devices/<pci_bus_id of PF0>/sriov_numvfs
+
+Vlan:
+ 1. RX side vlan stripping cannot be disabled on HW. Thus there is no
+ support for non-accelerated vlan on RX. If user disables vlan
+ stripping it will not ping.
+
+ 2. On TX side vlan normal/accelerated modes are supported.
+
+ a. To enable/disable TX vlan acceleration
+ #ethtool -K vlan-tx-offload on/off
+
+ b. To enable/disable RX vlan acceleration
+ #ethtool -K vlan-rx-offload on/off
