what do you think about that:
* store RSSI with it's associated time (ktime or jiffies?)
* when the RSSI is requested, send the request message to the wireless card
  (and don't wait for the response), and return the old RSSI if not too old,
  else return -ERESTARTSYS.

The ioctl should be re-called when we return -ERESTARTSYS, (at least I hope so).

Best regards
