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.
Currently, we are using: Trex v2.86 and dts from
http://git.dpdk.org/tools/dts/
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:

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
