-- TG reports min/avg/max latency values per stream direction, hence two
- sets of latency values are reported per test case; future release of
- TRex is expected to report latency percentiles.
-- Reported latency values are aggregate across two SUTs if the three
- node topology is used for given performance test; for per SUT latency,
- reported value should be divided by two.
-- 1usec is the measurement accuracy advertised by TRex TG for the setup
- used in FD.io labs used by CSIT project.
-- TRex setup introduces an always-on error of about 2*2usec per latency
- flow additonal Tx/Rx interface latency induced by TRex SW writing and
- reading packet timestamps on CPU cores without HW acceleration on NICs
- closer to the interface line.
