Bug Description
Sometimes the customer wants to keep VM's mtu=1500 to promote the performance, so we need:
1, setting mtu for phy nic which is used for the purpose of passing the VM's flow.
2, setting mtu for peer devices between br-phy and br-int.
Thus mtu inside VM can be set as 1500 via dhcp by configuring neutron's instance-mtu parameter.
huge frame (mtu > 1500) also require set mtu for tap device associated that VM, this effort doesn't include this aspect of the content. also:
1, only support ovs bridge
2, only support configuring the same mtu for all VMs, don't support mtu per network function.
