Hello, I am working on a test code for generating packets. I am using an old NIC (Intel x520-LR1). The port is bound to igb_uio. rte_eth_dev_info_get reports dev_info.max_tx_queues as 40 but the application is only configuring two tx queues (rte_eth_dev_configure). App feeds packets to both the queues. All packets are accounted for on the wire, but rte_eth_xstats_get show them only for queue-zero. See below, note the tx_q1 counts:
App Count: tx_count[0] = 744048640 tx_count[1] = 744046592 rte_eth_xstats_get: 0: rx_good_packets: 0 1: tx_good_packets: 1488095232 ..... 11: tx_q0packets: 1488095232 12: tx_q0bytes: 89285713920 13: tx_q1packets: 0 14: tx_q1bytes: 0 15: rx_crc_errors: 0 Same application when run inside a vm with vmxnet3 port, shows equal distribution between the two tx-queues. App Counts: tx_count[0] = 372023808 tx_count[1] = 372023808 rte_eth_xstats_get: 0: rx_good_packets: 2 1: tx_good_packets: 744047616 2: rx_good_bytes: 120 3: tx_good_bytes: 44642856960 ----- 11: tx_q0packets: 372023808 12: tx_q0bytes: 22321428480 13: tx_q1packets: 372023808 14: tx_q1bytes: 22321428480 15: rx_q0_drop_total: 0 16: rx_q0_drop_err: 0 Do I need to modify any configuration when running with real adapters for using both tx-queues? Appreciate your advise. Regards, Chaitanya.
