+ The bssid and ssid fields, if blank, will produce an unfiltered scan.
+ The type field will default to 3 (Any) and the keep field will default

Examples:
- 1) Perform an active scan on channels 1, 6, and 11 in the 'g' band:
- echo "chan=1g,6g,11g" > setuserscan
+ 1) Perform a passive scan on all channels for 20 ms per channel:
+ echo "dur=20" > setuserscan
- 2) Perform a passive scan on channel 11 for 20 ms:
- echo "chan=11gp dur=20" > setuserscan
+ 2) Perform an active scan for a specific SSID:
+ echo "ssid="TestAP"" > setuserscan
- 3) Perform an active scan on channels 1, 6, and 11; and a passive scan on
- channel 36 in the 'a' band:
-
- echo "chan=1g,6g,11g,36ap" > setuserscan
-
- 4) Perform an active scan on channel 6 and 36 for a specific SSID:
- echo "chan=6g,36a ssid="TestAP"" > setuserscan

+ 3) Scan all available channels (B/G, A bands) for a specific BSSID, keep
the current scan table intact, update existing or append new scan data:
echo "bssid=00:50:43:20:12:82 keep=1" > setuserscan
- 6) Scan channel 6, for all infrastructure networks.
+ 4) Scan for all infrastructure networks.
Keep the previous scan table intact. Update any duplicate BSSID/SSID
matches with the new scan data:
- echo "chan=6g type=1 keep=1" > setuserscan
+ echo "type=1 keep=1" > setuserscan
All entries in the scan table (not just the new scan data when keep=1)
will be displayed upon completion by use of the getscantable ioctl.
