You're going to
need more than just this revert though, since batman-adv calls
ether_setup, which will set min_mtu = 68, max_mtu = 1500, unless
batadv_hardif_min_mtu() always returns something 1500 or less.

It does only returns 1500 or less at the moment.

    return min_t(int, min_mtu - batadv_max_header_len(), ETH_DATA_LEN);

Actually,
looking at that, you could omit the mtu < 68 bit from
batadv_interface_change_mtu() too, since that'll already get done in the
core, but I have no clue what you need for max_mtu.

I would like to get this revert through net-next.git before anything else.

Kind regards,
