Also here, not sure it makes sense in cfg80211 level?

Though I'm not sure what the idea here is at all - you can refuse to
link switch etc, what would you use this for?

Then again, we haven't really designed out all the link selection stuff,
do we want wpa_s to do it, driver to do it, etc.? Hence debugfs. So
depending on what end up doing there, we will obviously need to
advertise some level of link-concurrency to userspace.
