Subject: ARM: dts: BCM5301X: EA9200: set WAN MAC from nvram
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=93214f2574126ee55494b4390ced5cd3f0e42aa9;p=thirdparty%2Fkernel%2Flinux.git

ARM: dts: BCM5301X: EA9200: set WAN MAC from nvram

The MAC address from the stock firmware is offset by 1. Define it
properly to avoid having to override it in userspace.
