Seeking help to configure DPDK 22 on Ubuntu 22.04.1 - "No probed ethernet devices"

[Nishant Verma]

Aniket, your both NIC's are supported.
just do one thing, bootup your server. run this sequence of the command and
share.
1) Reboot
2) ip a
3) lspci|grep Ether
4) lsmod | grep vfio
5) ./dpdk-devbind --status
6) ./dpdk-devbind -u <the PCI of 219  >
7) ./dpdk-devbind --status
8) ./dpdk-devbind -b vfio-pci <the PCI of 219  >

Make sure the vfio_pci is loaded if not load that before step 6.

Thanks.
