Actually, I have no reason to believe there *isn't* a device with
KEY_WIMAX... but we need the WWAN type before we bother with a WiMax
type :-)

IMO, we should fix the issue by adding a "supertype", i.e., a class.
Use that for generic grouping, and let type be more specific when there
is a reason for it. Repeat the class as the type to get a "generic"
type, when there is no reason to bother with more specific types.

Stuff like "WiMax", "802.1a", "EDGE", "GRPS", "802.1bg" would be the
type, and class would be "WLAN", "WWAN", etc.

We would only deal with classes on rfkill-input. Anything else more
specific should be done in userspace instead, disabling rfkill-input.
