Subject: mac80211: schedule the actual switch of the station before CSA count 0
From: Luciano Coelho <[email protected]>
commit ff1e417c7c239b7abfe70aa90460a77eaafc7f83 upstream.
Due to the time it takes to process the beacon that started the CSA
process, we may be late for the switch if we try to reach exactly
beacon 0. To avoid that, use count - 1 when calculating the switch time.
