Hi i40e driver experts, We are **not** a typical user of i40e dpdk driver, we are using tx Qos configuration (dcb) with strict latency tx queues. The feature stops working with a new firmware 7.0.x. We are using DDP (another thing that is not standard) to solve the drop rate issue.
dpdk 19.05 - works fine dpdk 20.02 (with new firmware) - does not work I tried to look into what changed between 19.05->20.02 that was related to dbc and couldn't find. Our patch is rather small, for now we have a workaround (allocating one more tx queue) but it has not solved the problem. more info here: https://github.com/cisco-system-traffic-generator/trex-core/issues/508 Does it ring a bell? -- Hanoh Sent from my iPhone
