negative.code: <1> Link must be up for TRex to work.
  <2> Average CPU utilization of transmitters threads. For best results it should be lower than 80%.
  <3> Gb/sec generated per core of DP. Higher is better.
  <4> Total Tx must be the same as Rx at the end of the run.
  <5> Total Rx must be the same as Tx at the end of the run.
  <6> Expected number of packets per second (calculated without latency packets).
  <7> Expected number of connections per second (calculated without latency packets).
  <8> Expected number of bits per second (calculated without latency packets).
