Bug ID: 1377
Summary: per queue counters are not working on Intel XL710
based SRIOV VFs using iavf pmd
Product: DPDK
Version: 22.11
Hardware: x86
OS: Linux
Status: UNCONFIRMED
Severity: normal
Priority: Normal
Component: ethdev
Assignee: dev@dpdk.org
Reporter: sahithi.sin...@oracle.com
Target Milestone: ---
Per queue counters are not working on Intel XL710 SRIOV VFs using iavf pmd in
both DPDK 21.11 and 22.11 version.
But per queue counters are populated when the same device is managed by iavf
kernel module.

=============================================
We also observed similar issue with PF devices of XL710 using i40e pmd and on
Intel 810-C series NICS using ice pmd .
Can someone please confirm whether this is DPDK pmd limitation or a NIC
specific limitation ? If [yes], can you also please point to the relevant
documentation .
