"VIRTCHNL_OP_1588_PTP_GET_CAPS" ops is sent by the VF to request PTP capabilities and responded by the PF with capabilities enabled for that VF. "VIRTCHNL_OP_1588_PTP_GET_TIME" ops is sent by the VF to request the current time of the PHC. The PF will respond by reading the device time and reporting it back to the VF.
