From 67b28148421a72532bc29f0b80c21d6aae2445f3 Mon Sep 17 00:00:00 2001 From: Gabor Juhos Date: Sat, 7 Jan 2012 17:24:44 +0000 Subject: [PATCH] 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.
