title: ScanResult capabilities interpretation
body: <p>I want to analyze the capabilities string of a ScanResult. However, the names ther are grouped in up to four square brackets e.g.</p>
  
  <pre><code>[WPA-PSK-TKIP+CCMP][WPA2-PSK-TKIP-CCMP][WPS][ESS]
  </code></pre>
  
  <p>Is there some kind of documentation describing which bracket relates to what, considering that some names may apear in various brackets. It would be great if there was a list of all possible capabilities somewhere as well. </p>
