Miroslav Lichvar	b1647dbcb7	ntp: wait for late HW TX timestamps ... When sending client requests to a close and fast server, it is possible that a response will be received before the HW transmit timestamp of the request itself. To avoid processing of the response without the HW timestamp, monitor events returned by select() and suspend reading of packets from the receive queue for up to 200 microseconds. As the requests are normally separated by at least 200 milliseconds, it is sufficient to monitor and suspend one socket at a time.	2018-02-02 11:36:38 +01:00

Miroslav Lichvar	997406fe47	ntp: add support for software timestamping on Linux ... Enable SCM_TIMESTAMPING control messages and the socket's error queue in order to receive our transmitted packets with a more accurate transmit timestamp. Add a new file for Linux-specific NTP I/O and implement processing of these messages there.	2016-11-10 15:26:56 +01:00
