Bug #27885
Allow VM Network Interface to use an MTU over 1500
Description
When assigning a VM to a Network Interface that has a MTU of 9000. The MTU of the bridge interface is fixed at 1500.
Error is as follows;
bridge1: invalid MTU: 9000(vlan51) != 1500

- if_bridge(4) set its MTU based on the first interface attached to it. So the logic here must be, physical interface MTU set on tap(4) and tap attached to if_bridge.
Without following the logic above, the bridge MTU will always be 1500 as well as tap. So interfaces with support to JUMBO FRAMES will never be attached to bridge.
