  LibvirtHybridOVSBridgeDriver to OVS VIF ports and VETH pairs

Status in OpenStack Compute (Nova):
  Fix Released

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.
