we could either remove the example level locks (or) keep the locks at
application level and disable them in service api through
rte_service_run_iter_on_app_lcore(<id>, 0).

If we choose to remove example level locks we could do something like
rte_service_run_iter_on_app_lcore(id, !rx_single)

Prod data is not needed I left it there to be consistent with the old example,
I will clean it up in the next version.
