Currently the DBus Interface.Scan API is counter-intuitive. It issues
ProbeRequests when doing passive scans when channels are specified, and
does not issue ProbeRequests for broadcast active scans.
This patch updates DBus API .Scan() logic per the test cases listed below:
1) Interface.Scan({'Type':'passive'})
Request: Passive scan (all channels)
Should be: No ProbeRequests; Passive Scan results for all channels
Previous: 1 ProbeRequest on all channels for both broadcast SSID and
selected network (scan_ssid=1)
This Patch: --No change--: 1 ProbeRequest on all channels for both
broadcast SSID and selected network (scan_ssid=1)
2) Interface.Scan({'Type':'passive', 'Channel':(2412, 20)})
Request: Passive scan (1 channel)
Should be: No ProbeRequests; Passive Scan results for 1 channel
(plus overlapping channels)
Previous: 1 broadcast ProbeRequest on specified channel
This Patch: --Fixed--: No ProbeRequests; Passive Scan results for 1
channel (plus overlapping channels)
3) Interface.Scan({'Type':'active'})
Request: Active scan with no SSIDs (all channels)
Should be: 1 broadcast ProbeRequest on all channels
Previous: No ProbeRequests; passive scan results for all channels
This Patch: --Fixed--: 1 broadcast ProbeRequest on all channels
4) Interface.Scan({'Type':'active', 'Channel':(2412, 20)})
Request: Active scan with no SSIDs (1 channel)
Should be: 1 broadcast ProbeRequest on specified channel
Previous: No ProbeRequests; Passive scan results for specified
channel (plus overlapping channels)
This Patch: --Fixed--: 1 broadcast ProbeRequest on specified channel
