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. ============================== "/sys/bus/pci/devices # ethtool -S eth1 NIC statistics: rx_bytes: 2880 rx_unicast: 0 rx_multicast: 0 rx_broadcast: 45 rx_discards: 0 rx_unknown_protocol: 0 tx_bytes: 0 tx_unicast: 0 tx_multicast: 0 tx_broadcast: 0 tx_discards: 0 tx_errors: 0 tx-0.packets: 3 tx-0.bytes: 266 rx-0.packets: 0 rx-0.bytes: 0 tx-1.packets: 0 tx-1.bytes: 0 rx-1.packets: 0 rx-1.bytes: 0 tx-2.packets: 0 tx-2.bytes: 0 rx-2.packets: 47 rx-2.bytes: 2820 tx-3.packets: 2 tx-3.bytes: 180 rx-3.packets: 0 rx-3.bytes: 0 /sys/bus/pci/devices # ethtool -i eth1 driver: iavf version: 5.15.0 firmware-version: N/A expansion-rom-version: bus-info: 0000:00:0a.0 supports-statistics: yes" "/sys/bus/pci/devices # lspci -n -s 00:0a.0 00:0a.0 0200: 8086:154c (rev 01)" ============================================= 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 .
