The fieldbus core doesn't have a configuration mechanism yet. This
patch adds one.
I deliberately omitted configuration when the core was added - I wanted to keep
complexity to a minimum. I'm sorry I didn't make this clearer.
As a result, the current core can only work with cards that either don't require
any config, or get it straight from the network/PLC. Profinet is a good example
of this. Most cards do require config however. So does the hms flnet card, which
I tried to add in the patchset.

Thanks for the heads-up! I will test that out.
