+
+ (C)Copyright 1997-1998 DAVICOM Semiconductor,Inc. All Rights Reserved.
+
+ Marcelo Tosatti <marcelo@...ectiva.com.br> :
+ Made it compile in 2.3 (device to net_device)
+
+ Alan Cox <alan@...rguk.ukuu.org.uk> :
+ Cleaned up for kernel merge.
+ Removed the back compatibility support
+ Reformatted, fixing spelling etc as I went
+ Removed IRQ 0-15 assumption
+
+ Jeff Garzik <jgarzik@...ox.com> :
+ Updated to use new PCI driver API.
+ Resource usage cleanups.
+ Report driver version to user.
+
+ Tobias Ringstrom <tori@...appy.mine.nu> :
+ Cleaned up and added SMP safety. Thanks go to Jeff Garzik,
+ Andrew Morton and Frank Davis for the SMP safety fixes.
+
+ Vojtech Pavlik <vojtech@...e.cz> :
+ Cleaned up pointer arithmetics.
+ Fixed a lot of 64bit issues.
+ Cleaned up printk()s a bit.
+ Fixed some obvious big endian problems.
+
+ Tobias Ringstrom <tori@...appy.mine.nu> :
+ Use time_after for jiffies calculation. Added ethtool
+ support. Updated PCI resource allocation. Do not
+ forget to unmap PCI mapped skbs.
+
+ Alan Cox <alan@...rguk.ukuu.org.uk>
+ Added new PCI identifiers provided by Clear Zhang at ALi
+ for their 1563 ethernet device.
+
+ TODO
+
+ Check on 64 bit boxes.
+ Check and fix on big endian boxes.
+
+ Test and make sure PCI latency is now correct for all cases.
