On the client, "chronyc ntpdata" should consistently show Hardware for
both "TX timestamping" and "RX timestamping". On the server, "chronyc
serverstats" should show increasing "NTP hardware RX timestamps" and
"NTP hardware TX timestamps". The number of daemon and kernel
timestamps should be incrementing only with new/restarted clients and
clients not using interleaved mode.
"chronyc serverstats" looks good: I'm seeing increasing "NTP hardware RX timestamps" and
"NTP hardware TX timestamps".
I'm now trying two clients, and I see different results with chronyc ntpdata:
- another CM4: here I see RX timestamping : Hardware but TX timestamping : Kernel
- an x86 box with the AQC107: here I see TX timestamping : Hardware and RX timestamping : Hardware
but on the client "chronyc ntpdata" shows Kernel for TX timestamping and RX timestamping.
I'm not quite sure what's going on..
