Specify maxpoll for HW timestamping (default minpoll + 1) to track the PHC well even when there is little NTP traffic on the interface. After each PHC reading schedule a timeout according to the maxpoll. Polling between minpoll and maxpoll is still triggered by HW timestamps. Wait for the first HW timestamp before adding the timeout to avoid polling PHCs on interfaces that are enabled in the configuration but not used for NTP. Add a new scheduling class to separate polling of different PHCs to avoid too long intervals between processing I/O events.
