If that occurs - the following can be seen from ptp4l: - - ptp4l[4756.840]: timed out while polling for tx timestamp - ptp4l[4756.840]: increasing tx_timestamp_timeout may correct this issue, - but it is likely caused by a driver bug - ptp4l[4756.840]: port 1 (p2p1): send sync failed - ptp4l[4756.840]: port 1 (p2p1): MASTER to FAULTY on FAULT_DETECTED - (FT_UNSPECIFIED) - - This can confuse users because it implies this is a bug, when the - correct solution in many cases is to just increase the timeout to - a slightly higher value. - - Since we know this is a problem for many drivers and hardware designs, - lets increase the default timeout. - - Note that a longer timeout should not affect setups which return the - timestamp quickly. On modern kernels, the poll() call will return once - the timestamp is reported back to the socket error queue.
