wl1271: Optimize scan duration
Currently then dwell times for each channel in scans is set to an overly long value, and excessive number of probe-requests are transmitted on each channel (for active scans.) Based on testing, comparable results can be received with smaller dwell-time, and, with fever probe-requests - in fact, reducing the number of probe-requests to 2 seems to increase the number of found results. Configure more optimal values for per channel dwell times. Comparison for the different scan configurations (in my current office environment): dwell-time 60000 3x probe-req == ~60 results 40000 3x probe-req == ~50 results 30000 3x probe-req == ~40 results dwell-time 60000 2x probe-req == ~70 results 40000 2x probe-req == ~60 results 30000 2x probe-req == ~58 results The above are results for a cumulative 3 scan run. For individual scans, the number of results drop slightly more.
