Yes Bruce, rte_eth_tx_burst api returns the same count as nb_pkts (4th-arg) Thanks for pointing out the information on tracking per-queue stats mapping, can try this out. Thanks & Regards, Rajasekhar On Fri, Feb 17, 2023 at 10:09 PM Bruce Richardson < bruce.richard...@intel.com> wrote: > On Fri

Hi Stephen, Have tx queue len was 1024, increasing it to 2048 hasn't changed the behaviour. IXIA is the receiver in this case, which is definitely(and tested) capable of receiving more rate than this. IXIA-TX --->RX(ixgbe-port0)HOST(ixgbe-port1)TX ---> IXIA-RX Captured the rx packets count at ixgb

Ok Stephen, thanks for the information, I can try that. One of the problems I see with single Tx Queue mode is that Ixia reports packet drops, though I confirmed with the help of counters (before invoking tx burst) that all packets are being sent-out. Dumping HW counters don't report any drops in

Multiple Tx-Queues not working as expected

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
