From c048aaf4ca854fa67a3bfa9dab5b9ddc5083b3b7 Mon Sep 17 00:00:00 2001 From: Jiri Pirko Date: Fri, 13 Mar 2009 11:47:48 -0700 Subject: 8139cp: allow to set mac address on running device So far there was not a chance to set a mac address on running 8139cp device. This is for example needed when you want to use this NIC as a bonding slave in bonding device in mode balance-alb. This simple patch allows it. Signed-off-by: Jiri Pirko Signed-off-by: David S.
