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 adds plug/unplug when using ovs vif 'OVS_ACCELERATION'. The plug method will lookup the VF representor and connect it to 'br-int', while the unplug method will remove the VF representor from 'br-int'.
