Adding PF and VF action support for octeontx2 Flow.
If RTE_FLOW_ACTION_TYPE_PF action is set from VF, then the packet
will be sent to the parent PF.
If RTE_FLOW_ACTION_TYPE_VF action is set and original is specified,
then the packet will be sent to the original VF, otherwise the packet
will be sent to the VF specified in the vf_id.
