Hi, currently the mtu size of batman-adv soft-interfaces is limited to ETH_DATA_LEN (1500 bytes) in function batadv_hardif_min_mtu as far as I understand. A comment in this function states that batman-adv "does not support MTUs bigger than ETH_DATA_LEN". Is there a specific reason for this or would it be possible to increase the MTU size to something like 1518 by simply replacing all limitations to ETH_DATA_LEN with a higher value?
