> virtchnl
> definitions
>
> PTP capabilities are negotiated using virtchnl commands. There are two
> available modes of the PTP support: direct and mailbox. When the direct
> access to PTP resources is negotiated, virtchnl messages returns a set of
> registers that allow read/write directly. When the mailbox access to PTP
> resources is negotiated, virtchnl messages are used to access PTP clock and to
> read the timestamp values.
>
> Virtchnl API covers both modes and exposes a set of PTP capabilities.
>
> Using virtchnl API, the driver recognizes also HW abilities - maximum
> adjustment of the clock and the basic increment value.
>
> Additionally, API allows to configure the secondary mailbox, dedicated
> exclusively for PTP purposes.
