like, literally. that's the whole personality. a new interface shows up with a smaller MTU than what we had and she's like "not on my watch" and adjusts it. queen behavior 👑

🦋 SYNOPSIS 🦋

void batadv_update_min_mtu (struct net_device *mesh_iface );

that's it. that's the whole signature. no return value, she gives nothing back because she's too busy slaying 😌
