> Support for allowing VF to negotiate the descriptor format requires that the VF
> specify which descriptor format to use when requesting Rx queues.
> The VF is supposed to request the set of supported formats via the new
> VIRTCHNL_OP_GET_SUPPORTED_RXDIDS, and then set one of the supported
> formats in the rxdid field of the virtchnl_rxq_info structure.
> 
> The virtchnl.h header does not provide an enumeration of the format values. The
> existing implementations in the PF directly use the values from the DDP package.
> 
> Make the formats explicit by defining an enumeration of the RXDIDs.
> Provide an enumeration for the values as well as the bit positions as returned by
> the supported_rxdids data from the VIRTCHNL_OP_GET_SUPPORTED_RXDIDS.
