I was going to add this to the real patch:

The new API is to reduce some of the clutter in the applications. Most of
the applications need to do the following:

    int ret = rte_eal_init(argc, argv);
    if ( ret < 0 )
        rte_exit(EXIT_FAILURE, "rte_eal_init: failed!");
    argc -= ret;
    argv += ret;

    ret = parse_args(argc, argv);
    if ( ret < 0 )
        rte_exit(EXIT_FAILURE, "parse_args:failed!");

With this new API:

    int ret = rte_eal_init_parse(argc, argv, parse_args);
    if ( ret < 0 )
        rte_exit(EXIT_FAILURE, "rte_eal_init_parse: Failed!");
