OK! I didn't see it here and I guess I didn't look at the latest version
yet, or I missed it.

You might be able to do that with hwsim? There are multi-bssid test
cases in the hostap repository, and CSA test cases as well, so I guess
it'd be possible to come up with a combined one.

I'm not *too* worried about this though - we're still all testing and
developing this.
