ar71xx: local mac support on the wndr3700
The wndr3700 at least has no eth0 mac address and usually leverages
the first wireless device's mac when in a bridged scenario. If,
however, you want to route, and not bridge the interfaces, you
need a unique mac address for it.
This patch sets the local bit on the mac address pulled from the
wireless chip and uses the resulting address for eth0.
