 * provide a function to just pass in the whole beacon/probe response
   frame and pick it apart itself
 * handle aging
 * provide a wext "set scan" hook that creates a request and passes it
   off to ->scan(), provide wext "get scan" hook

   on the bitrate information the wiphy provides

 * use all those helpers I mentioned above

Also, we need to think about
 * how fullmac stuff can integrate, can it provide this IE-based
   information, and if not, is it feasible to just synthesize it?
 * whether this should really be per wiphy as it is now, or somehow more
   per netdev, or not related to a netdev at all...
