[Olsr-dev] Idea for small OLSR improvement

maybe (in addtion to pinging) verify if olsrd packets from the other side
arrive regulary (ideally log all seqnr of them (tcpdump|grep[|sed] is
enough), so u can independently calculate lq based on this,...)?

imho it `s quite likely that if pings work, olsrd braocast packets will work
aswell, ..
if so, there would be non influence on olsr/routing from any layer <=2
(which means you problem is probably inside olsr and/or its config)
