Properly respect other configured MTUs for other vlans. Properly respect parent of vlan MTU if configured. Also avoid errors when possible. This helps VLANs MTU handling but all the other interfaces as gre/gif/... needs the same handling. It is better to require reboot on MTU changes especially on complex configurations.
