I turned on mTCP dpdk port of CONFIG_RTE_LIBRTE_ETHDEV_DEBUG trace, I think the issue is intel 82571EB only support 1 RX/TX queue, but mtcp/src/dpdk_module.c passed CONFIG.num_cores (2) to rte_eth_dev_configure, so I got trace log:
Initializing port 0... PMD: rte_eth_dev_configure: ethdev port_id=0 nb_rx_queues=2 > 1
EAL: Error - exiting with code: 1
Cause: Cannot configure device: err=-22, port=0
so the question is what is the best way to pass on correct RX/TX queue from mtcp/src/dpdk_module.c to dpdk rte_eth_dev_configure ?

I resolved it by add 'num_cores = 1' in epwet.conf, sorry for the noise
