[B.A.T.M.A.N.] bug - unregister_netdevice: usage_count = 1

Hi all, I found a bug playing with my interfaces while bat0 was active. The bug is described here: http://www.open-mesh.org/issues/148 The steps to reproduce it are reported too. In a few words, when trying to unregister a device by unloading its module, the modprobe hangs and in the dmesg I can

[B.A.T.M.A.N.] [PATCH 2/2] batman-adv: Ensure that we really have route changes in update_route

The debug output of update_route has tests for "route deleted" and "route added". All other situations are handled as "route changed". This is not true because neigh_node and curr_router could be both NULL. The function is not called in this situation, but the code might be interpreted wrong when

One of the first actions of gw_election is to check whether curr_gw is not NULL. In that case it will jumps to out. The rest of the code (before out) can now assume that gw_node is NULL. Therefore the router is only changed when curr_gw_tmp. This makes some printks in this block unnecessary which h
