Hi Simon,
I think that forcing a particular command line order is not that clean. It
might be better to remove the cfg->master_lcore setting from
eal_parse_coremask(), and defer the selection of the master lcore until all of
the command-line options have been parsed. If ?master-lcore was specified,
save the value and use that, otherwise rte_get_next_lcore(-1, 0, 0) can return
the first bit set in the coremask.
