[PATCH libmlx5 0/7] Completion timestamping

[Yishai Hadas <yishaih-VPRAkNaXOzVWk0Htik3J/w@public.gmane.org>]

Hi Doug,

This series from Matan and me implements the libibverbs
'Completion timestamping' API.

It can serve as some vendor code to justify the new API,
from both clarity and performance aspects.

As already pointed,
Benchmarks we ran in our test lab found that this new approach generally
equals to current API but *not* worse than. As the new API enables
extending the polled fields we can overall say that it's a better API than
the legacy one.
