[Linuxptp-users] Buggy driver for I210 ?

[Xavier B. <xav...@fr...>]

Hi all,

I'm running ptp4l 1.6 (default config, slave-only) on a debian with
kernel 4.2.0-1-amd64, device is an Intel I210; I saw that in the logs:

nov. 27 16:32:32 pcxav ptp4l[14249]: [1925038.115] master offset         -5 s2 freq  -25072 path delay       534

Is the driver really buggy or is it something else in my setup ?

Thanks,
