This change is for the PHC devices that can measure the phase offset between PHC signal and the external signal, such as the 1PPS signal of GNSS. Reporting PTP_CLOCK_EXTOFF to user space will be piggy-backed to the existing ptp_extts_event so that application such as ts2phc can poll the external offset the same way as extts. Hence, ts2phc can use the offset to achieve the alignment between PHC and the external signal by the help of either SW or HW filters.
