  Dear bug triager. This bug was created since a commit was marked with DOCIMPACT.
  Your project "openstack/neutron" is set up so that we directly report the documentation bugs against it. If this needs changing, the docimpact-group option needs to be added for the project. You can ask the OpenStack infra team (#openstack-infra on freenode) for help if you need to.

      hardware offload support for openvswitch
      
      In Kernel 4.8 we introduced Traffic Control (TC see [1]) hardware offloads
      framework for SR-IOV VFs which allows us to configure the NIC [2].
      Subsequent OVS patches [3] allow us to use the TC framework
      to offload OVS datapath rules.
      
      This patch allow OVS mech driver to bind direct (SR-IOV) port.
      This will allow to offload the OVS flows using tc to the SR-IOV NIC
      and gain accelerate OVS.
