While running DPDK QoS sample application for single packet flow configuration as mentioned in Section "122.2. Test Case: 1 pipe, 8 TCs" of https://doc.dpdk.org/dts/test_plans/qos_sched_test_plan.html, I am facing below Tx Queue setup error (-22).

Have used E810-CQDA2 and the same has been bound (PF) with DPDK igb_uio driver.

Also, there is no CONFIG_RTE_SCHED_COLLECT_STATS flag in dpdk-stable-21.11.2, whereas I have seen RTE_SCHED_COLLECT_STATS in config/rte_config.h. So, I have enabled them as #define RTE_SCHED_COLLECT_STATS. Is this adequate to run DPDK QoS? Or do we need to define anywhere in app side also, dpdk-stable-21.11.2/examples/qos_sched?

~/dpdk-stable-21.11.2/examples/qos_sched/build# ./qos_sched -l 1,2,3 -n 4 -- -i --pfc "0,1,2,3" --cfg ../profile.cfg

Expectation is to see the below result as mentioned in DPDK qos_sched_test_plan.html,
