Hi Team, I am trying to set-up 8 Tx-Queues (but only 1 Rx-Queue) and burst traffic out of different Tx-Queues from the same cpu core on an ixgbe nic (10G). Although transmitted packets reach the peer, reading the statistics indicates only the Tx-q[0] has non-zero packets and bytes count, the rest of the Tx-q[1] to Tx-q[7] all have zero packets and bytes count. I am following the below sequence. 1. configuration rte_eth_dev_configure(port-id, 1 /* only 1 rx-q */, 8 /* tx-queues */, &dev_conf /* memset of 0 on this dev_conf done */); 2. tx queue set-up struct rte_eth_dev_info dev_info; rte_eth_dev_info_get(port-id, &dev_info); struct rte_eth_txconf tx_conf; memcpy(&tx_conf, &dev_info.default_txconf, sizeof tx_conf); for(i=0; i<8; i++) { rte_eth_tx_queue_setup(port-id, i /* queue-id */, 1024 /* num_of_txdesc */, numa_node, &tx_conf;) } 3. rx queue set-up rte_eth_rx_queue_setup(port-id, 0, 1024 /* num_of_rxdesc */, &rx_conf, mbuf_pool); 4. start the port rte_eth_dev_start(port-id); 5. call the below tx burst function with different queue-id (range 0 to 7) every-time for every burst of new packets to be transmitted rte_eth_tx_burst(port-id, queue-id, pkts_burst, nb_pkts_burst); 6. read stats using rte_eth_xstats_get and verified that only the first tx-q has non-zero packets and bytes count, rest of the tx-q's have 0 packets and bytes count. What could be wrong here? Appreciate any help. Thanks & Regards, Rajasekhar ReplyForward
