    ltq-vdsl-app: set MAC address for vectoring error reports
    
    This tells the modem about the WAN MAC address, which is used as source
    address for vectoring error reports that are generated by the firmware.
    
    It needs to be set early, as the MEI driver only actually writes the
    value to the modem when is in reset state (i.e. the firmware has been
    loaded, but connection has not started yet).
