Like bgscan, autoscan is an optional module based feature to automate scanning but while disconnected or inactive. Instead of requesting directly a scan, it only sets the scan_interval and the sched_scan_interval. So, if the driver supports sched_scan, autoscan will be able to tweak its interval. Otherwise, the tweaked scan_interval will be used. If scan parameters needs to be tweaked, an autoscan_params pointer in wpa_s will provide those. So req_scan / req_sched_scan will not set the scan parameters as they usually do, but instead will use this pointer. Modules will not have to request a scan directly, like bgscan does. Instead, it will need to return the interval it wants after each notification. Signed-hostap: Tomasz Bursztyka <tomasz.bursztyka@linux.intel.com>
