A single Sync sample whose receive timestamp was taken late, for example because the task was scheduled late with software timestamping, was fed straight into the phase correction and the drift estimate, and could pull the clock away from the master. - Add CONFIG_NETUTILS_PTPD_OUTLIER_THRESHOLD_NS (default 0, which disables the check). A phase error that differs by more than this many nanoseconds from the median of the last five accepted samples is discarded, with a warning. - Accept the sample after eight consecutive rejections and restart the history from it, so that a real step of the master is still followed while a short burst of disturbed samples is ridden out. - Restart the history whenever the clock is stepped, since the old samples no longer describe the new time base. - With the default of 0 the behaviour is unchanged.
