Hello,

I found your question on dpdk so i try to on my setup that didnt give any error. Try to update your driver.

My setup:

ubuntu 20.04.3 LTS

Kernel 5.4.0-110-generic

dpdk Version dpdk-stable-20.11.3

Intel e810-C

Driver ice-1.8.8.tar

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,
