The hardware knows what frequencies it supports. Unfortunately this has
to be a somewhat dynamic thing, as this is often not queryable until the
device firmware is up and running.
This can be accomplished by passing a static table to the
register_wiphy_device() call (or perhaps via a struct wiphy_dev
parameter) or through a more explicit, dynamic interface like:
wiphy_register_supported_frequency(hw, 2412).
For completely programmable hardware, the stack should interact with a
module like ieee80211_geo, to help ensure the hardware stays within
legal limits.
