Reported-by: syzbot+b21a54...@syzkaller.appspotmail.com
batman_adv: batadv0: The MTU of interface vlan28 is too small (1500) to handle the transport of batman-adv packets. Packets going over this interface will be fragmented on layer2 which could impact the performance. Setting the MTU to 1560 would solve the problem.
batman_adv: batadv0: Not using interface vlan28 (retrying later): interface not active

the code is fine but needs lockdep annotation.
