When scanning on passive channels the firmware uses frag_passive_dwell to define the maximum continuous scan time before returning to the operating channel. On active channels max_out_time is the parameter used by the firmware to define the maximum time allowed out of the operating channel. Since active channels' scan should also be fragmented set max_out_time equal to frag_passive_dwell. In addition: - Set max_out_time and suspend_time if the firmware doesn't support fragmented scan to avoid unexpected behavior. - Adjust max_out_time for second level of scan precedence.
