From: Thierry Reding treding@nvidia.com
Pass the ethernet MAC address to the kernel upon boot. This passes both the local-mac-address property (as passed to U-Boot from cboot) and the currently set MAC address via the mac-address property. The latter will only be set if it is different from the address that was already passed via the local-mac-address property.
