Just curious but why the XL710 / i40e name mismatch?

i40e stands for Intel 40 GbE Ethernet which is more generic than naming
the driver the same as the first part (XL710).  That way when future
silicon is made, we are not stuck with a driver named after previous
silicon.

Too bad if also means that when 100 comes out
this driver won't be expected to work.

ixgbe is a good example.  ixgbe is the driver name, but it supports the
82598, 82599 / X520, and X540 chips.

It will work for our 40GbE parts definitely, as far as future technology
and silicon, I cannot say.

From the intro and most of the rest of the patches:

----------------------------
This series implements the new i40e driver for Intel's upcoming
Intel(R) Ethernet Controller XL710 Family of devices.
----------------------------

If the xl710 is a specific instance of the i40e family,
I think this is incorrect.

Another good example is e100, e1000, e1000e, and igb. :-)

+Linux Base Driver for the Intel(R) Ethernet Controller XL710 Family
+===================================================================
+
+Intel i40e Linux driver.
+Copyright(c) 2013 Intel Corporation.
+
+Contents

+
+Identifying Your Adapter
+========================
+
+The driver in this release is compatible with the Intel Ethernet
+Controller XL710 Family.
+
+For more information on how to identify your adapter, go to the Adapter &
+Driver ID Guide at:
+
+    http://support.intel.com/support/network/sb/CS-012904.htm
+
+
+Enabling the driver
+===================
+
+The driver is enabled via the standard kernel configuration system,
+using the make command:
+
+     Make oldconfig/silentoldconfig/menuconfig/etc.
+
+The driver is located in the menu structure at:
+
+	-> Device Drivers
+	  -> Network device support (NETDEVICES [=y])
+	    -> Ethernet driver support
+	      -> Intel devices
+	        -> Intel(R) Ethernet Controller XL710 Family
+
+Additional Configurations
+=========================
+
+  Generic Receive Offload (GRO)
+  -----------------------------
+  The driver supports the in-kernel software implementation of GRO.  GRO has
+  shown that by coalescing Rx traffic into larger chunks of data, CPU
+  utilization can be significantly reduced when under large Rx load.  GRO is
+  an evolution of the previously-used LRO interface.  GRO is able to coalesce
+  other protocols besides TCP.  It's also safe to use with configurations that
+  are problematic for LRO, namely bridging and iSCSI.
+
+  Ethtool
+  -------
+  The driver utilizes the ethtool interface for driver configuration and
+  diagnostics, as well as displaying statistical information. The latest
+  ethtool version is required for this functionality.
+
+  The latest release of ethtool can be found from
+  https://www.kernel.org/pub/software/network/ethtool
+
+  Data Center Bridging (DCB)
+  --------------------------
+  DCB configuration is not currently supported.
+
+  FCoE
+  ----
+  Fiber Channel over Ethernet (FCoE) hardware offload is not currently
+  supported.
+
+  MAC and VLAN anti-spoofing feature
+  ----------------------------------
+  When a malicious driver attempts to send a spoofed packet, it is dropped by
+  the hardware and not transmitted.  An interrupt is sent to the PF driver
+  notifying it of the spoof attempt.
+
+  When a spoofed packet is detected the PF driver will send the following
+  message to the system log (displayed by  the "dmesg" command):
+
+  Spoof event(s) detected on VF (n)
+
+  Where n=the VF that attempted to do the spoofing.
+
+
+Performance Tuning
+==================
+
+An excellent article on performance tuning can be found at:
+
+http://www.redhat.com/promo/summit/2008/downloads/pdf/Thursday/Mark_Wagner.pdf
+
+
+Known Issues
+============
+
+
+Support
+=======
+
+For general information, go to the Intel support website at:
+
+    http://support.intel.com
+
+or the Intel Wired Networking project hosted by Sourceforge at:
+
+    http://e1000.sourceforge.net
+
+If an issue is identified with the released source code on the supported
+kernel with a supported adapter, email the specific information related
+to the issue to e1000-devel@lists.sourceforge.net and copy
+netdev@vger.kernel.org.
