Hi Ajit,
We have a 25G Broadcom NIC that is installed on an Arm machine.
And I am running into a problem when I try to run nic_single_core_perf on the NIC.
All the NICs are up and running when testing.
The problem is an error when I try to run the test case inside the nic_single_core_perf:
TestNicSingleCorePerf: Test running at parameters: framesize: 64, rxd/txd: 512

trex.common.trex_exceptions.TRexError: *** [RPC] - Failed to get server response from tcp://172.18.0.40:4501
I also try to run TRex in stateless mode with./t-rex-64 -i --cfg /etc/trex_cfg.yaml and connect with ./trex-console
Then start sending traffic with command
trex>start -f stl/imix.py
But this will cause an error to turn off Trex.

I believe if everything is working, this should not turn off trex but please correct me if I am wrong.
I wonder if you have any suggestion of how I can approach this issue?
Best,
David
