Feature:
NETWORK test in new hwcert-client changes the bandwidth portion of the TCP testing to try different parallelism settings: 2, 4, and 8 in and attempt to verify transmission at 80% of the interface speed.
Reason:
Result (if any):
If this goal is not met, warning messages are logged. The test passes so long as bw_tcp does not produce errors.

I want to add some remarks: - To get a result near the maximum throughput it's best to have eight (8) parallel streams. I have also tested with lower and higher values but it figured out that the configuration based on eight streams shows the best performance. - The taskset command is most useful when the defined CPU core belongs to the CPU that is providing the PCIe lanes for the Infiniband adapter (in my case QLE7340).

network test patch to apply bandwidth goal to tcp bandwidth testing
The patch changes the bandwidth portion of the TCP testing to try different parallelism settings: 2, 4, and 8 in and attempt to verify transmission at 80% of the interface speed.
If this goal is not met, warning messages are logged. The test passes so long as bw_tcp does not produce errors.
