I just stumbled across an omission. In the section

   21.8. Serving NTP Time With PTP

there is configuration example for ptp4l where phc2sys will be
adjusting the PTP clock (eth3 in the example).

In such a case, you also want to have the option "free_running 1",
just in case ptp4l should lose the best master clock algorithm.
Otherwise, ptp4l and phc2sys will both adjust the eth3 clock at the
same time.

Thanks,
