Hello,

I have been experiencing issues with an Intel E810-CQDA2 and Ubuntu Server 20.04 on DPDK 21.10 and 22.03 :

Command used :
sudo ./dpdk-testpmd -l 1-7 -n 4 -a 17:00.0 -- --socket-num=0 --burst=10 --txd=1024 --rxd=1024 --mbcache=512 --rxq=1 --txq=1 --nb-cores=1 --txpkts=1500 -i --txonly-multi-flow --forward-mode=txonly --tx-ip=10.10.1.168,239.0.0.8

Output:
EAL: Detected CPU lcores: 8
EAL: Detected NUMA nodes: 1
EAL: Detected static linkage of DPDK
EAL: Multi-process socket /var/run/dpdk/rte/mp_socket
EAL: Selected IOVA mode 'PA'
EAL: VFIO support initialized
TELEMETRY: No legacy callbacks, legacy socket not created
testpmd: No probed ethernet devices
Fail: input rxq (1) can't be greater than max_rx_queues (0) of port 0
EAL: Error - exiting with code: 1
  Cause: rxq 1 invalid - must be >= 0 && <= 0

It seem that the Nic isn't detected by DPDK when running the tests, but when I run dpdk-devbind

$ dpdk-devbind.py -s

Network devices using DPDK-compatible driver
============================================
0000:17:00.0 'Ethernet Controller E810-C for QSFP 1592' drv=igb_uio unused=ice,vfio-pci

I don't understand why I can't use the device although it is binded to DPDK.

Thanks for your help,
