Recently the bridge was changed to automatically set maximum MTU on port events (add/del/changemtu) when vlan filtering is enabled, but that actually changes behaviour in a way which breaks some setups and can lead to packet drops. In order to still allow that maximum to be set while being compatible, we add the ability for the user to tune the bridge MTU up to the maximum when vlan filtering is enabled, but that has to be done explicitly and all port events (add/del/changemtu) lead to resetting that MTU to the minimum as before.
