+Subject: [DPDK 16/17] common/iavf: add flow director support in virtual
+ channel
+
+Adds new ops and structures to support VF to add/delete/validate/
+query flow director.
+
+ADD and VALIDATE FDIR share one ops: VIRTCHNL_OP_ADD_FDIR_FILTER.
+VF sends this request to PF by filling out the related field in
+virtchnl_fdir_add. If the rule is created successfully, PF
+will return flow id and program status to VF. If the rule is
+validated successfully, the PF will only return program status
+to VF.
+
+DELETE FDIR uses ops: VIRTCHNL_OP_DEL_FDIR_FILTER.
+VF sends this request to PF by filling out the related field in
+virtchnl_fdir_del. If the rule is deleted successfully, PF
+will return program status to VF.
+
+Query FDIR uses ops: VIRTCHNL_OP_QUERY_FDIR_FILTER.
+VF sends this request to PF by filling out the related field in
+virtchnl_fdir_query. If the request is successfully done by PF,
+PF will return program status and query info to VF.
