Then perhaps we should replace WiMAX with the WWAN type?

In the discussion around the WiMAX addition I do remember people wanted
it to have a seperate key code because it was "different technology". Wouldn't that
be the same for all WWAN technologies?
Aka, should the WiMAX keycode be changed to a WWAN keycode in input.h
and then be used for all WWAN rfkill switches?
