> The new capability is gated by VIRTCHNL_VF_CAP_PTP, which must be set by the
> VF to request access to the new operations. In addition, the
> VIRTCHNL_OP_1588_PTP_CAPS command is used to determine the specific
> capabilities available to the VF.
> 
> This support includes the following additional capabilities:
> 
> * Rx timestamps enabled in the Rx queues (when using flexible advanced
>   descriptors)
> * Read access to PHC time over virtchnl using
>   VIRTCHNL_OP_1588_PTP_GET_TIME
> 
> Extra space is reserved in most structures to allow for future extension (like set
> clock, Tx timestamps).  Additional opcode numbers are reserved and space in the
> virtchnl_ptp_caps structure is specifically set aside for this.
> Additionally, each structure has some space reserved for future extensions to
> allow some flexibility.
