Hmm; it could be that NM needs to do channel -> freq conversion here.
It's a bit undefined whether drivers pass back the channel or the
frequency.  So I guess NM needs to handle both.  There's defined
semantics in the iw_float part to flag whether the returned value is a
channel or a frequency.

Another possibility is that the driver has some issue with getting the
frequency off the card periodically.
