If MAC timestamping is sufficient, I think the Intel I210/211 would be a good choice. It's well supported, timestamping is stable to few tens of nanoseconds and asymmetries are already compensated in the driver. It has PPS input/output, so you can verify the accuracy. -- Miroslav Lichvar _______________________________________________ Linuxptp-users mailing list Linuxptp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-users
