Hm, we technical guys tend to associate "frontend" with the channel
decoder / tuner combination but the average user can can easily assume
that the frontend is the entire card. He has no idea what the functions
of the chips are.
But ack, we should be as precise as possible.
So the next question is: If we have the entries you propose, how do these
get reported to user space? Currently, the API only reports the frontend
type.
