If rte_service_private.h needs the rte_cycles.h then I think it can be
included in rte_service_private.h.

Should we add socket_id as well in the service name?

sw_pmd_log?

Should we also check rte_service_is_running() in sw pmd start function
to verify application did everything to setup the service function on
service lcore? or means for feedback?
