3.13.11-ckt12 -stable review patch. If anyone has any objections, please let me know.
------------------ 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.
