    pfilter: accept unicast ARP frames · 835437ae
    Alessandro Rubini authored
    This commit removes the requirement for ARP frames to be broadcast
    in the no-vlan case.  The simplified rule-set of a vlan setup already
    accepts ARP unicast, and no harm is done.
    Although we do not make ARP  requests so we won't receive unicast
    replies, hosts do send unicast requests, to refresh an ARP entry
    that is going to expire.
    The next commit enacts this feature in software, as a side effect
    of supporting pdelay PTP.
