Bug Description

Due to this missing functionality MTU can not be increased/adapted to specific requirements.
For example configure compute node VIFs to make use of jumbo frames.

LinuxOVSInterfaceDriver and LinuxBridgeInterfaceDriver are using network_device_mtu to configure the MTU of some created VIFs.

Howto get this patch backported for havanna? I just found https://wiki.openstack.org/wiki/Documentation/HowTo#Git_commit_messages_and_backports but the commit-sg doesn't contain the backport line. So what's the process for backports in this case?
