From: Sunil Kumar Kori <sk...@marvell.com>
Example commands to run UT and check the traces with babeltrace viewer.
- Delete the existing /root/dpdk-traces/ directory if needed.
> sudo rm -rf /root/dpdk-traces/
- Start the dpdk-test
> sudo ./build/app/test/dpdk-test -c 0x3 - --trace=.*
- Run trace_autotest
> trace_autotest
- View the traces with babletrace viewer.
> sudo babeltrace /root/dpdk-traces/
