Date: Fri, 13 Mar 2009 18:58:35 +0100 From: Jiri Pirko <jpirko@...hat.com> To: linux-kernel@...r.kernel.org Cc: ivecera@...hat.com, jgarzik@...ox.com, davem@...emloft.net, netdev@...r.kernel.org Subject: [PATCH] 8139too: allow to set mac address on running device Similar patch as for 8139cp posted yesterday, so the same comment: So far there was not a chance to set a mac address on running 8139too 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.
