Add new VIRTCHNL_VF_OFFLOAD_RX_FLEX_DESC flag, opcode VIRTCHNL_OP_GET_SUPPORTED_RXDIDS and add member rxdid in struct virtchnl_rxq_info to support AVF Flex RXD extension. Add support to allow VF to query flexible descriptor RXDIDs supported by DDP package and configure Rx queues with selected RXDID for IAVF. Add code to allow VIRTCHNL_OP_GET_SUPPORTED_RXDIDS message to be processed. Add necessary macros for registers.
