Subject: [PATCH] ramips: fix GL-inet GL-MT300N-V2 WAN/LAN MAC address

Correct MAC address lookup to appropriate offset based on vendor
source.

Override the WAN MAC to use the same address as LAN. The switch driver
increments the base MAC address for the WAN vlan but the stock firmware
uses the same MAC address for all interfaces.

Based on vendor source commit
