Log Message:
ARP/ND6: Revert prior

Turns out some people actually use this behaviour and strictly speaking
it is allowed by RFC5227 2.4 where it says:

   At any time, if a host receives
   an ARP packet (Request *or* Reply) where the 'sender IP address' is
   (one of) the host's own IP address(es) configured on that interface,
   but the 'sender hardware address' does not match any of the host's
   own interface addresses, then this is a conflicting ARP packet

The key part is "any of the host's own interface addreses".
