From: Sujith Manoharan <[email protected]> The start time field in the NoA attribute needs to be updated based on the TSF timer when an absence notification is sent by the P2P GO. When two channel contexts are active, continuous, cyclic NoA is announced by setting the count value to 255, but the start time is updated only once, for one beacon and the same value is sent in all subsequent beacons, even though the timestamp keeps moving.
Fix this by removing the check for 'periodic_noa_duration' and assign the interface's start_time/duration values directly when there is more than one active context.
