From: Johannes Berg <johannes.berg@xxxxxxxxx>
Add a few tests to validate what happens with connections
while an AP is doing CSA:
- quiet to diff channel (shouldn't connect)
- quiet to same channel (shouldn't connect)
- non-quiet to diff channel (shouldn't connect)
- non-quiet to same channel (should connect)
