Thanks for your answer Shahaf !
We're trying to measure the latency of packets going through various service
chains inside individual "server". Eg. we can see that on Server 1, the
latency for the service chain handling HTTP packets is ~800ns (+ max and mins,
tail latency, etc). What we do no

Thanks for the details.
The use case is clear. We will take it internally to see when we can support it.
AFAIK we cannot read the internal time from userspace.

Actually I managed this patch to implement support for
rte_eth_timesync_read_time.
Please tell me potential modifications, and if I shall submit it again as a
"normal" patch to dev ?

Playing w/ meson build I got to know that the binary name for testpmd got

Not sure if it was discussed or not before, but such change will affect all the

What is the reason for the change in the name?
