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).
