I also think the timeout could be a bit smaller but just to make sure we all 
agree on one thing: The fragmentation should never be used over lossy links.

Imagine we have a link with 50% packet loss and fragmentation enabled which 
makes out of every packet 2 packets. Now, we have a pretty high probability 
that one of these 2 packets gets lost during transit. Therefore batman-adv can 
not reassemble the packet on the other side which will lead to a 
retransmission that has the same chance of success as the previous packet ...
