These ARP request are not issued by BATMAN itself. BATMAN does only send
broadcast packets - your system creates these requests.

BATMAN askes the system for the IP and broadcast addresses. In both cases the
system responds with the same answer. I don't see much difference from
batmans point of view.

You have multihomed OLSR nodes with a single IP and that works ? Can anyone of
the OLSR folks say something about that ? I can't imagine how the routing
daemon can distinguish 2 distinct connections with the same address ...
