Modification List
---------- ------------------------------------------------
+ 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
+ 03-15-2006 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
+ 03-27-2005 Tim, Add the internal state machine reset
+ Sten, If multicast address more than 4, enter PROM mode
+ Changed rdc to r6040
12-22-2004 Sten Init MAC MBCR register=0x012A
