I'm crafting my own packets in mbuf's (74 byte packets all) and sending it using ret = rte_eth_tx_burst(port_ids[lcore_id], 0, m_pool,burst_size); When burst_size is 1, it does work. Work in the sense the NIC will continue with sending packets, at a little over 50 percent of the link rate. For 1000 Mbps link rate .....The observed transmit rate of the NIC is 580 Mbps (using Intel DPDK). But it should be possible to achieve at least 900 Mbps transmit rate with Intel DPDK and I350 on 1 Gbps link. Could someone help me out on this ? Thanks and regards
