Any suggestions?
There is currently no option to tell timemaster it shouldn't use HW timestamping when it's available. I think the only way is to define a dummy PTP domain which would take HW timestamping on the interface first and the real domain would be left with SW timestamping as only one domain per interface can use HW timestamping. E.g.: [ptp_domain 1] interfaces eth0 [ptp_domain 0] interfaces eth0 Domain 1 would use HW timestamping on eth0, but if there is no master in domain 1 on your network, it wouldn't do anything. -- Miroslav Lichvar ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Linuxptp-users mailing list Linuxptp-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/linuxptp-users
