This epic tracks all the effort needed to deliver the solution related to the bug described below.

Problem Description: Clearly explain the issue.

ice driver: run iperf ipv4 test failed when running ovs or ovs dpdk qinq svlan case on rhel10.0

Impact Assessment: Describe the severity and impact (e.g., network down,availability of a workaround, etc.).

When configure the ovs qinq svlan topo, it can ping successfully, but do iperf test fail. This issue only occur on ice driver of rhel10.0. It has no issue on rhel9.4. It also has no issue on other driver cards(i40e,mlx5_core) on rhel10.0.

Software Versions: Specify the exact versions in use (e.g.,openvswitch3.1-3.1.0-147.el8fdp).

kernel-6.12.0-36.el10
openvswitch3.3-3.3.0-21.el10fdp.x86_64

Issue Type: Indicate whether this is a new issue or a regression (if a regression, state the last known working version).

It has no issue on rhel9.4, but it has issue on rhel10.0. so It should be a regression bug.

Reproducibility: Confirm if the issue can be reproduced consistently. If not, describe how often it occurs.

It can reproduced.

Reproduction Steps: Provide detailed steps or scripts to replicate the issue.

Expected Behavior: Describe what should happen under normal circumstances.

It run do iperf ipv4 test successfully on rhel10.0.

Observed Behavior: Explain what actually happens.

on rhel10.0.
do iperf ipv4 address failed.
do iperf ipv6 address successfully.

on rhel9.4:
do both iperf ipv4 and ipv6 address succeefully.

when do the iperf ipv4 test on rhel9.4, catch the packet in the port of guest as following.
