    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
