It works if the MTU is explicitly set in the zone configuration. If the MTU is set on the bridge to something else than 1500 and the zone configuration has 'auto', then the MTU of all other interfaces and bridges is still set to 1500. Shouldn't we try to get the MTU of the bridge when it's set to 'auto' and then setup the other interfaces accordingly? Or am I misunderstanding what 'auto' does?
