Oh, and linuxptp is running on eth0, no bridges are set up. linuxptp is started with "/usr/sbin/ptp4l -f /etc/linuxptp.cfg" # cat /etc/linuxptp.cfg # LinuxPTP configuration file for synchronizing the system clock to # a remote PTP master in slave-only mode. # # By default synchronize time in slave-only mode using UDP and hardware time # stamps on eth0. If the difference to master is >1.0 second correct by # stepping the clock instead of adjusting the frequency. # # If you change the configuration don't forget to update the phc2sys # parameters accordingly in linuxptp-system-clock.service (systemd) # or the linuxptp SysV init script.
