hardware offload support for openvswitch

Browse Source 
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 rule

This patch adds the VIF_TYPE_OVS_ACCELERATION
to portbindings
