The reason is when switch connection, disconnect operation happened on the 1st AP, then 11d scan start command sent to firmware, and then a new hw scan arrived for the 2nd AP. The 11d scan is running at this moment, so the hw scan can not start immediately, it needs to wait the 11d scan finished, it increased the time cost of switch AP and even happened scan fail as log below after apply the incoming patch.

Then the time cost of switching AP is small and not happened scan fail.
