Modification List
---------- ------------------------------------------------
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
