Moshe Levi 2a09ede8fb 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 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'.
