++ This driver is for RDC R6040 FastEthernet MAC series.
++ For kernel version after 2.4.22
++
++ 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
++ 03-15-2006 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
