21 (C)Copyright 1997-1998 DAVICOM Semiconductor,Inc. All Rights Reserved.
23 Marcelo Tosatti <marcelo@conectiva.com.br> :
24 Made it compile in 2.3 (device to net_device)
26 Alan Cox <alan@redhat.com> :
27 Cleaned up for kernel merge.
28 Removed the back compatibility support
29 Reformatted, fixing spelling etc as I went
30 Removed IRQ 0-15 assumption
32 Jeff Garzik <jgarzik@pobox.com> :
33 Updated to use new PCI driver API.
34 Resource usage cleanups.
35 Report driver version to user.
37 Tobias Ringstrom <tori@unhappy.mine.nu> :
38 Cleaned up and added SMP safety. Thanks go to Jeff Garzik,
39 Andrew Morton and Frank Davis for the SMP safety fixes.
41 Vojtech Pavlik <vojtech@suse.cz> :
42 Cleaned up pointer arithmetics.
43 Fixed a lot of 64bit issues.
44 Cleaned up printk()s a bit.
45 Fixed some obvious big endian problems.
47 Tobias Ringstrom <tori@unhappy.mine.nu> :
48 Use time_after for jiffies calculation. Added ethtool
49 support. Updated PCI resource allocation. Do not
50 forget to unmap PCI mapped skbs.
52 Alan Cox <alan@redhat.com>
53 Added new PCI identifiers provided by Clear Zhang at ALi
54 for their 1563 ethernet device.
58 Check on 64 bit boxes.
59 Check and fix on big endian boxes.
61 Test and make sure PCI latency is now correct for all cases.
