    batman-adv: enable fast client detection using unicast_4addr packets
    
    The "early client detection mechanism" can be extended to find new clients by
    means of unicast_4addr packets.
    
    The unicast_4addr packet contains as well as the broadcast packet (which is
    currently used in this mechanism) the address of the originating node and can
    therefore be used to install new entries in the Global Translation Table
