When binding i40e VF to iavf, because the PF doesn't support VIRTCHNL_VF_OFFLOAD_ADV_RSS_PF capability. Therefore, the VF hashing cannot be enabled. This patch adds support of hash configuration for i40e VF by sending VIRTCHNL_OP_SET_RSS_HENA message to the PF after checking that the PF does not support VIRTCHNL_VF_OFFLOAD_ADV_RSS_PF capability.
