Check NIC datasheet if some thing you think is correct and still not working. For DCB, you can check example(vmdq_dcb) present in example folder in DPDK. For Flow Director, you can check test-pmd code. Just for your information. flow director can be used like this " struct rte_eth_fdir_filter entry; memset(&entry, 0, sizeof(struct rte_eth_fdir_filter)); entry.input.flow_type = 0x05; entry.input.flow.udp4_flow.ip.dst_ip=0x11223344; entry.input.flow.udp4_flow.dst_port=0x1111; entry.action.rx_queue=0x02; entry.action.report_status=0x02; ret = rte_eth_dev_filter_ctrl(0, RTE_ETH_FILTER_FDIR, RTE_ETH_FILTER_ADD, &entry); " So, from now packet received from 0x11223344 will be re-directed to queue 2.
