To be clear this is a HW test so the fact that it shows up in CI as
green means just that the 2 sub cases (per [1]) which the CI judged
to be stable and passing are still passing. The other 10 sub cases
have never passed and still don't. IDK if you QEMU doesn't support
RSS or it's something else but AFAICT this patch doesn't appear to
make a difference to us.

You can see the per-case breakdown of the history here (including
the ignored sub-cases):
