Please cover both IGMPv3 and MLDv2 since the patchset touches both. You
can add the MLDv2 tests in bridge_mld.sh.

Also, I think you can simplify the test by simply matching on the
expected values of MRC and QQIC using tc-u32.

For both IGMPv3 and MLDv2 please test both:

* MRC and QQIC in linear range.
* MRC and QQIC in non-linear range.

And please make sure the new test cases don't add new shellcheck
warnings / errors or it will fail in the CI. You can ignore existing
ones.
