+
+	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
