Hi Ajit,

I'm running into a problem with trying to run nic_single_core_perf on the new NIC.
The current configuration uses trex version v2.82.
However, I'm running into an error when it tries to actually do a test case in the nic_single_core_perf.

The output looks like this when it reaches a test case:

TestNicSingleCorePerf: Test running at parameters: framesize: 64, rxd/txd: 512

I have found one similar case on the github repository for trex, but the solution was vendor-specific: https://github.com/cisco-system-traffic-generator/trex-core/issues/147.
Have you ran into this issue before?

Thanks,
Brandon
