Hi Pavel, I think mistake is here: -int eth_configure_ret = rte_eth_dev_configure(current_port, tx_queues, rx_queues, &default_port_conf); +int eth_configure_ret = rte_eth_dev_configure(current_port, rx_queues, tx_queues, &default_port_conf); according to http://dpdk.org/doc/api/rte__ethdev_8h.html#ac30d075b4b206c7122e200164ce69893 second arg is number of rx queues
