This ticket is tracking the QE verification effort for the solution to the problem described below.
Problem Description: Clearly explain the issue.
i40e: run iperf ipv4 test failed sometimes when running ovs dpdk tunnel function test
Impact Assessment: Describe the severity and impact (e.g., network down,availability of a workaround, etc.).
Software Versions: Specify the exact versions in use (e.g.,openvswitch3.1-3.1.0-147.el8fdp).
openvswitch3.6-3.6.0-12.el10fdp.fdpqe1601.9.x86_64
openvswitch3.6-3.6.0-12.el9fdp.x86_64
Issue Type: Indicate whether this is a new issue or a regression (if a regression, state the last known working version).
It is not a regression issue, it exist on previous version.
Reproducibility: Confirm if the issue can be reproduced consistently. If not, describe how often it occurs.
It can reproducibility.
Reproduction Steps: Provide detailed steps or scripts to replicate the issue.
Run ovs dpdk tunnel function test:
server i40e <-connect-> client i40e
