Title:
  [RFE] SR-IOV accelerated OVS integration

Status in neutron:
  Fix Released

Bug description:
  SR-IOV accelerated Open vSwitch significantly improves the performance of OVS while maintaining its core functionality.
  The idea is to leverage SR-IOV technology with OVS control plane management.

  Change on the neutron side:
  1. extend the OVS mechanism driver to bind direct port

  The vif change are:
  The mechanism driver will send new vif type to nova which will create hostdev interface (SR-IOV VF passthrough) and will look up the SR-IOV VF representor and plug it to the br-int

  kernel changes for tc offloading support are merged in 4.8
  ovs patches for using tc offloading  can be found here https://patchwork.ozlabs.org/patch/738176/
