Supported by the local hardware.
To see the rate supported by the BSS, you will need Scanning
support (this is a relatively new feature - see my web page).
David has not yet integrated this feature in the driver. Also,
the Lucent firmware doesn't report the rates of the BSS, and I could
not find how to get Scanning to work on Symbol firmware, so you need a
PrismII firmware (or to use the airo or poldhu driver which already
support Scanning).
