After argument parsing done by rte_eal_init(), the remaining arguments are to be parsed by the application by progressing in the argv array. In this context, the first string represented by argv[0] is still the same program name as the original argv[0], while the next strings are the application arguments. This is because rte_eal_init() manipulates the argv array after EAL parsing, before returning to the application.
