FYI, we noticed that this is a backport commit of upstream 205704c618af0ab2366015d2281a3b0814d918a0 (merged by v5.10), so we also test this case on mainline, and this issue doesn't exist.
Can you test the latest linux-5.4.y branch and see whether the issue exists on there?
You can pull from:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git linux-5.4.y
The HEAD commit is:
de0cd3ea700d1e8ed76705d02e33b524cbb84cf3 ("Linux 5.4.210")
The issue doesn't exist on latest head of linux-5.4.y branch
Sorry, I made a mistake, the issue still exists on linux-5.4-y head.
Thanks for testing, unfortunately, I am not the committer nor author of the offending commit. This should have been reported to the netdev list.
I have added them to the CC list. Can you resend the reproducer and detailed test output with them CC'ed?

for this stat, only cae90bd22cffb can pass the test, while 2ef23e860e765 and v5.4.210 all failed.
FYI, I found a backported commit with a Fixes tag contains 205704c618af (commit upstream):
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=...
But the 5.4.y HEAD that already includes that commit still fails based on your report. Let's wait for netdev people' response on this. As the mainline doesn't have this issue, maybe something need to get backported?
Summary:
These commits only live in 5.4.x stable branch (backport from upstream):
