batman-adv: consider network coding overhead when calculating required mtu
The module prints a warning when the MTU on the hard interface is too small to transfer payload traffic without fragmentation. The required MTU is calculated based on the encapsulation header size. If network coding is compild into the module its header size is taken into account as well.
