Not sure if this is an issue.
It is an issue. The two ports of the NIC don't share the same PHC, so there needs to be something keeping them in sync (phc2sys -a) and ptp4l needs to be told to not verify the PHC index numbers. That's the boundary_clock_jbod option. Don't expect best accuracy in this setup. -- Miroslav Lichvar _______________________________________________ Linuxptp-users mailing list Linuxptp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-users
