V3: * Suggest from Richard Cochran, time_keep work is COMPLETELY INDEPENDENT from time stamping, let it always run. In .fec_ptp_gettime() function will return an error when ptp physical clock is disabled. V2: * As Richard Cochran's suggestion, use schedule_delayed_work instead of period timer. * Stop delayed work before ipg clock disable like suspend, ethx close.
