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
|
||||
PHY_CAP = 0x01E1
|
||||
|
||||
Need to Do LIst:
|
||||
1. If multicast address more than 4, use the multicast address hash
