Hm, let's ask the other way around:
What is the advantage of doing this in kernelspace?
- guarantee that all frontends behave the same, so we had a real,
device independent, API?
- define an API which covers all possibilities (input ranges, ...), so
we don't need additional, private IOCTLs?
- pass results in a good way to the userspace? For example, a blocking
read of a "frontend parameter" structure which returns new found
transponders? Is this flexible enough?
