    ramips: update Tenbay T-MB5EU wireless MAC address
    
    The current MAC address assignment is still incorrect.
    
    Use the same MAC address as seen on the stock firmware
    for both wireless interfaces.
    
    The 5GHz MAC address OUI is +2 in the first EUI octet. We currently
    don't do this in OpenWrt. Ignore this offset for now. With the current
    assignment, recurring MAC addresses between radios is already taken care
    of.
