This problem already exists, e.g. with ptpv2-l4-event vs ptpv2-l2-event. We could say that all hardware that cannot timestamp all packets is broken, but it's so common that it has to be supported. If the hardware which cannot timestamp all event messages is very rare, ok, maybe it's not worth the trouble. However, timestamping only sync messages has an advantage with very large number of clients as they don't have timestamp each other's delay requets and timestamping of sync messages is more reliable. -- Miroslav Lichvar _______________________________________________ Linuxptp-devel mailing list Linuxptp-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-devel
