43 Donald Becker - he wrote the original driver, kudos to him!
44 (but please don't e-mail him for support, this isn't his driver)
46 Tigran Aivazian - bug fixes, skbuff free cleanup
48 Martin Mares - suggestions for PCI cleanup
50 David S. Miller - PCI DMA and softnet updates
52 Ernst Gill - fixes ported from BSD driver
54 Daniel Kobras - identified specific locations of
57 Gerard Sharp - bug fix, testing and feedback
59 David Ford - Rx ring wrap fix
61 Dan DeMaggio - swapped RTL8139 cards with me, and allowed me
64 Donald Becker/Chris Butterworth/Marcus Westergren -
65 Noticed various Rx packet size-related buglets.
67 Santiago Garcia Mantinan - testing and feedback
69 Jens David - 2.2.x kernel backports
71 Martin Dennett - incredibly helpful insight on undocumented
74 Jean-Jacques Michel - bug fix
76 Tobias Ringström - Rx interrupt status checking suggestion
78 Andrew Morton - Clear blocked signals, avoid
79 buffer overrun setting current->comm.
81 Kalle Olavi Niemitalo - Wake-on-LAN ioctls
83 Robert Kuebel - Save kernel thread from dying on any signal.
