Hi, So the problem is that the kernel clock support for ptp hardware clocks was not backported until 6.4, and I wouldn't even trust its backport until at least 6.5
I've done some decent validation of Intel stuff on 6.5 and it works well enough, but you have to trust that Redhat backported the complex feature correctly. 6.3 could do software timestamping, that really is about all.
