I'm looking into it further, but it looks like the X722 (which uses the i40e driver) does not record RX timestamps on layer 2 1588 event packets where the version is set to 2.1 rather than 2.
I found this issue previously reported last year (https://www.mail-archive.com/linuxptp-users@lists.sourceforge.net/msg02414.html). I believe this is the root cause. An easy workaround is to manually patch linuxptp to set version 2.0. -cliff _______________________________________________ Linuxptp-users mailing list Linuxptp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-users
