Currently IDPF supports only mailbox access to PHC operations and
Tx timestamping, however the driver shall also be able to handle direct
access. The difference is that PHC/timestamps actions are performed
directly, through BAR registers, instead of sending a virtchnl message to
CP. Registers offsets are negotiated with the CP during the capabilities
negotiation.
