CSIT performance tests. TRex stateless mode is used to measure NDR and
PDR throughputs using MLRsearch and to measure maximum transer rate
in MRR tests.

- If the TRex is not already installed on TG, it is installed in the
suite setup phase - see `TRex installation`_.

profiles. The traffic is sent and the statistics obtained using
If measurement of latency is requested, two more packet streams are
created (one for each direction) with TRex flow_stats parameter set to
STLFlowLatencyStats. In that case, returned statistics will also include
