-				Theory of Operation
-
-I. Board Compatibility
-
-This device driver is designed for the Intel i82557 "Speedo3" chip, Intel's
-single-chip fast Ethernet controller for PCI, as used on the Intel
-EtherExpress Pro 100 adapter.
-
-II. Board-specific settings
-
-PCI bus devices are configured by the system at boot time, so no jumpers
-need to be set on the board.  The system BIOS should be set to assign the
-PCI INTA signal to an otherwise unused system IRQ line.  While it's
-possible to share PCI interrupt lines, it negatively impacts performance and
-only recent kernels support it.
-
-III. Driver operation
-
-IIIA. General
-The Speedo3 is very similar to other Intel network chips, that is to say
-"apparently designed on a different planet".  This chips retains the complex
-Rx and Tx descriptors and multiple buffers pointers as previous chips, but
-also has simplified Tx and Rx buffer modes.  This driver uses the "flexible"
-Tx mode, but in a simplified lower-overhead manner: it associates only a
-single buffer descriptor with each frame descriptor.
-
-Despite the extra space overhead in each receive skbuff, the driver must use
-the simplified Rx buffer mode to assure that only a single data buffer is
-associated with each RxFD. The driver implements this by reserving space
-for the Rx descriptor at the head of each Rx skbuff.
-
-The Speedo-3 has receive and command unit base addresses that are added to
-almost all descriptor pointers.  The driver sets these to zero, so that all
-pointer fields are absolute addresses.
-
-The System Control Block (SCB) of some previous Intel chips exists on the
-chip in both PCI I/O and memory space.  This driver uses the I/O space
-registers, but might switch to memory mapped mode to better support non-x86
-processors.
-
-IIIB. Transmit structure
-
-The driver must use the complex Tx command+descriptor mode in order to
-have a indirect pointer to the skbuff data section.  Each Tx command block
-(TxCB) is associated with two immediately appended Tx Buffer Descriptor
-(TxBD).  A fixed ring of these TxCB+TxBD pairs are kept as part of the
-speedo_private data structure for each adapter instance.
-
-The newer i82558 explicitly supports this structure, and can read the two
-TxBDs in the same PCI burst as the TxCB.
-
-This ring structure is used for all normal transmit packets, but the
-transmit packet descriptors aren't long enough for most non-Tx commands such
-as CmdConfigure.  This is complicated by the possibility that the chip has
-already loaded the link address in the previous descriptor.  So for these
-commands we convert the next free descriptor on the ring to a NoOp, and point
-that descriptor's link to the complex command.
-
-An additional complexity of these non-transmit commands are that they may be
-added asynchronous to the normal transmit queue, so we disable interrupts
-whenever the Tx descriptor ring is manipulated.
-
-A notable aspect of these special configure commands is that they do
-work with the normal Tx ring entry scavenge method.  The Tx ring scavenge
-is done at interrupt time using the 'dirty_tx' index, and checking for the
-command-complete bit.  While the setup frames may have the NoOp command on the
-Tx ring marked as complete, but not have completed the setup command, this
-is not a problem.  The tx_ring entry can be still safely reused, as the
-tx_skbuff[] entry is always empty for config_cmd and mc_setup frames.
-
-Commands may have bits set e.g. CmdSuspend in the command word to either
-suspend or stop the transmit/command unit.  This driver always flags the last
-command with CmdSuspend, erases the CmdSuspend in the previous command, and
-then issues a CU_RESUME.
-Note: Watch out for the potential race condition here: imagine
-	erasing the previous suspend
-		the chip processes the previous command
-		the chip processes the final command, and suspends
-	doing the CU_RESUME
-		the chip processes the next-yet-valid post-final-command.
-So blindly sending a CU_RESUME is only safe if we do it immediately after
-after erasing the previous CmdSuspend, without the possibility of an
-intervening delay.  Thus the resume command is always within the
-interrupts-disabled region.  This is a timing dependence, but handling this
-condition in a timing-independent way would considerably complicate the code.
-
-Note: In previous generation Intel chips, restarting the command unit was a
-notoriously slow process.  This is presumably no longer true.
-
-IIIC. Receive structure
-
-Because of the bus-master support on the Speedo3 this driver uses the new
-SKBUFF_RX_COPYBREAK scheme, rather than a fixed intermediate receive buffer.
-This scheme allocates full-sized skbuffs as receive buffers.  The value
-SKBUFF_RX_COPYBREAK is used as the copying breakpoint: it is chosen to
-trade-off the memory wasted by passing the full-sized skbuff to the queue
-layer for all frames vs. the copying cost of copying a frame to a
-correctly-sized skbuff.
-
-For small frames the copying cost is negligible (esp. considering that we
-are pre-loading the cache with immediately useful header information), so we
-allocate a new, minimally-sized skbuff.  For large frames the copying cost
-is non-trivial, and the larger copy might flush the cache of useful data, so
-we pass up the skbuff the packet was received into.
-
-IV. Notes
-
-Thanks to Steve Williams of Intel for arranging the non-disclosure agreement
-that stated that I could disclose the information.  But I still resent
-having to sign an Intel NDA when I'm helping Intel sell their own product!

-   To minimize the disruption -- the previous command might have already
