test/trace: add functional test cases
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/ Signed-off-by: Sunil Kumar Kori <skori@marvell.com> Acked-by: David Marchand <david.marchand@redhat.com>
