Hi Yang Tao
Thanks for your reply.
Actually, I am using "uio_pci_generic" as driver.
when I query the bind status, I got "drv=uio_pci_generic" like following image.
Is there anything else we can do to debug this issue?

You can try the uio_pci_generic, don’t use the VFIO-PCI driver.
modprobe uio
modprobe uio_pci_generic
dpdk-devbind.py  -b uio_pci_generic xxxx

Hi Community:
There is a problem when I use dpdk-testpmd to execute io mode test.
Issue description: No packet was sent out successfully.
testpmd cmdline: dpdk-testpmd -l 1,2,3 -n 4 -- -i

test mode setup:"set fwd io" then "start"

Statistics: No packet was send out.

Environment:
ThinkCentre-E77+ubuntu22.04 64bit@kernel 5.11.0-27-generic + dpdk 22.11.1 + Intel I226 network adapter
Network topology: connect port1 to port2 directly with network cable(No switch was involved).
