Optimally the number of channels should be auto-discovered. I like to make
the configuration as automatic as possible.
So if the hardware can be safely probed for the number of channels, or
announces the number of channels, that would be best.
Otherwise a command line option would work.Perhaps:
--rapavybus=0xf0000000:6
The syntax i fairly arbitrary, but it should be relatively intuitive or
consistent.
