Once a while a driver will give us a bogus MAC address. This can be remedied by the user by setting the MAC address on the wlanX interface, but unfortunately one cannot change the address of the wmasterX interface which results in wlanX going up but wmasterX refusing to. This is pretty bad. This patch forces wmasterX to have a valid MAC address. The actual address doesn't matter at all.
