Subject: Can not initialize Intel XX710-DA2 on Ubuntu 22.04

I have been having some issues trying to make an Intel XXV710-DA2 on Ubuntu Server 22.04 working using either DPDK 21.10 and 22.03.
When I run the following command :
sudo ./dpdk-testpmd -l 1-7 -n 4 -a 65:00.0,txqs_min_inline=1,tx_pp=500 -- --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 --eth-peer=0,01:00:5e:00:00:08 --tx-ip=,

I get that 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
EAL: Probe PCI driver: net_i40e (8086:158b) device: 0000:65:00.0 (socket 0)
eth_i40e_dev_init(): Failed to init adminq: -66
ethdev initialisation failed
EAL: Requested device 0000:65:00.0 cannot be used
EAL: Bus (pci) probe failed.
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 seems that DPDK can't initialize the Nic. Did anybody already tested this particular Nic with Ubuntu Server 22.04 ? Was it successful ?

Thanks in advance,
