The issue can be reproduced with example program l2fwd by modifying it
to sleep 1 second before launching thread.


code like this:
        ....
        check_all_ports_link_status(nb_ports, l2fwd_enabled_port_mask);

        sleep(1);
        /* launch per-lcore init on every lcore */
        rte_eal_mp_remote_launch(l2fwd_launch_one_lcore, NULL, CALL_MASTER);
        RTE_LCORE_FOREACH_SLAVE(lcore_id) {
                if (rte_eal_wait_lcore(lcore_id) < 0)
                        return -1;
        }
        ....
