From 3d6593e9cc40d0eacc03f75f90834794a4a477df Mon Sep 17 00:00:00 2001 From: Kevin Hao Date: Tue, 26 May 2009 20:49:03 -0700 Subject: [PATCH] net/ucc_geth: allow to set mac address on running device Inspired by the patch for 8139too (bda6a15a). Currently we can't set mac address on a running ucc_geth device. But this is needed when you use this device as a bonding slave in bonding device in balance-alb mode. So add this feature for ucc_geth device. Signed-off-by: Kevin Hao Signed-off-by: David S.
