I fear that this might lead to a strange user experience. If the mtu on batX
wasn't set explicitely but the mtu of an interface used by batman is increased
while batman uses it the user has to know that he/she now needs to manually
modify the batX mtu before it becomes effective.
What about a flag which remembers whether the mtu on batX was modified by the
user. If so, batman-adv does not increase the mtu otherwise we keep the
current behaviour ?

Marek
