-	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
