Hi, I'm seeing what looks like benign errors from qdisc on testpmd & our DPDK app on Azure. I'm wondering if anyone knows of a way to 'fix' these?
EAL: Detected 8 lcore(s) EAL: Detected 1 NUMA nodes EAL: Detected static linkage of DPDK EAL: Selected IOVA mode 'VA' EAL: Probing VFIO support... EAL: VFIO support initialized EAL: Probe PCI driver: mlx5_pci (15b3:1016) device: 2a8d:00:02.0 (socket 0) EAL: Probe PCI driver: mlx5_pci (15b3:1016) device: 5ed7:00:02.0 (socket 0) net_vdev_netvsc: probably using routed NetVSC interface "eth1" (index 3)* * *tap_nl_dump_ext_ack(): Cannot delete qdisc with handle of zero** * *tap_nl_dump_ext_ack(): Failed to find qdisc with specified classid** * *tap_nl_dump_ext_ack(): Failed to find qdisc with specified classid** * *tap_nl_dump_ext_ack(): Failed to find qdisc with specified classid** * *tap_nl_dump_ext_ack(): Failed to find qdisc with specified classid** * *tap_nl_dump_ext_ack(): Failed to find qdisc with specified classid** * *tap_nl_dump_ext_ack(): Failed to find qdisc with specified classid** * *tap_nl_dump_ext_ack(): Failed to find qdisc with specified classid** * *tap_nl_dump_ext_ack(): Failed to find qdisc with specified classid* [...] It's not causing any issues that I can see, I'm just wondering if there's a cause for this in the environment that we can fix so we don't have benign errors showing up. Reproduced by running testpmd with no arguments on Azure: - OS: Ubuntu 20.04 5.4.0-1048-azure - DPDK: 20.11.1 (LTS) - Networking: Azure Accelerated Networking (netvsc) OS setup is pretty minimal, nothing special other than DPDK is installed. I don't recall these errors happening while on bare metal - only on Azure. Thanks! Regards, Tyler
