* Portions of this code are taken from the Linux forcedeth driver that was
* based on a cleanroom reimplementation which was based on reverse engineered
* documentation written by Carl-Daniel Hailfinger and Andrew de Quincey:
* Copyright (C) 2003,4,5 Manfred Spraul
* Copyright (C) 2004 Andrew de Quincey (wol support)
* Copyright (C) 2004 Carl-Daniel Hailfinger (invalid MAC handling, insane
* IRQ rate fixes, bigendian fixes, cleanups, verification)
* Copyright (c) 2004,2005,2006,2007,2008,2009 NVIDIA Corporation
*
* The probe, remove, open and close functions, along with the functions they
* call, are direct copies of the above mentioned driver, modified where
* necessary to make them work for iPXE.
*
* The poll and transmit functions were completely rewritten to make use of
* the iPXE API. This process was aided by constant referencing of the above
* mentioned Linux driver. This driver would not have been possible without this
* prior work.
