In general, batman-adv adds a little header of 24 Bytes. But this kind of extra cost also applies to packets between batman nodes, not only when a packet comes from the connected network. So if you are bridging any other networks/hosts into the mesh network (i.e. bridging eth0 + bat0) does not matter, you should just a) increase the MTU of the mesh-interfaces to 1524 which is usually not a problem for wifi interfaces or b) decrease the MTU on all hosts to 1476 (usually not so do-able).
Would you happen to know what the maximum MTU you could use on the wireless interface?
For example, if I have an ethernet network that can support jumbo frames like on a gigabit interface, how large of an MTU could I use on the wireless interface. In my case I'm using Atheros wireless devices, so I don't know if that matters.
