---------- ------------------------------------------------
+ 10-07-2007 Clean up the driver using checkpatch
08-24-2006 Support at linux 2.6.10 above
03-24-2006 Support NAPI
- 03-21-2006 By Charies,change spin_lock_irqsave(lp->lock, flags) to
- spin_lock_irqsave(&lp->lock, flags) in set_multicast_list
+ 03-21-2006 By Charies,change spin_lock_irqsave(lp->lock, flags)
+ to spin_lock_irqsave(&lp->lock, flags)
+ in set_multicast_list
03-15-2006 Modify the set_multicast_list ,due to when re-plug the ethernet,
it will forget the previous setting
- 07-12-2005 Tim, modify the set_multicast_list
- 03-28-2005 Tim, modify some error mac register offset in
- function set_multicast_list
+ 07-12-2005 Tim, modify the set_multicast_list
+ 03-28-2005 Tim, modify some error mac register offset in
