     Examples:

-            echo "chan=1g,6g,11g" > 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 "chan=1g,6g,11g,36ap" > 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.
