Hello All,

When adding an interface the bridge interface's MTU is set to the
minimum of all the interfaces. Call to dev_set_mtu(br->dev, br_min_mtu(br))
in br_add_if() achieves that. But when deleting an interface from the bridge
the MTU is not reset again to the minimum of the current set of interfaces.
Is there a reason it is that way ?

If not I could send a patch that resets the MTU with a call to
dev_set_mtu(br->dev, br_min_mtu(br)) in br_del_if().

Looking forward to your response.

Thanks.

Venkat
