Why to stop ports *before* making sure all lcores are stopped?
Shouldn't that peace of code be identical for both poll and event mode?
Something like:
rte_eal_mp_wait_lcore();

                RTE_ETH_FOREACH_DEV(portid) {
                        if ((enabled_port_mask & (1 << portid)) == 0)
                                continue;
                        rte_eth_dev_stop(portid);
                        rte_eth_dev_close(portid);
                }
?
