We see these too on a 7.0 box (amd64).

My theory is that this is a response to ARP requests.  ARP requests are
broadcast, so the BSD box hears someone asking for this IP, but cannot
find it on any local interfaces, and so complains that it cannot
construct a proper reply.

Have not tested it though.
