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. johannes
