- fix "rtnl locked" concurrent executions by using rtnl_lock instead of
rtnl_trylock. This fix enables batman-adv initialisation to do not fail just
because somewhere else in the system another code path is holding the rtnl
lock. It is easy to see the problem when batman-adv is trying to start
together with other networking components.
- fix the routing protocol forwarding policy by enhancing the duplicate control
packet detection. When the right circumstances trigger the issue, some nodes in
the network become totally unreachable, so breaking the mesh connectivity.
- fix the Bridge Loop Avoidance component by not running the originator address
change handling routine when the component is disabled. The routine was
generating useless packets that were sent over the network.
