Arg, I can't read German (at least not Technical German) so I makes things
more complicate for me :)

I am going to read this. It makes me thinking about time quantas as describe
in Documentation/networking/can.txt:

708 <http://www.mjmwired.net/kernel/Documentation/networking/can.txt#708>       
   "tq 125 prop-seg 6 phase-seg1 7 phase-seg2 2 sjw 1"
709 <http://www.mjmwired.net/kernel/Documentation/networking/can.txt#709>       
        Shows
the time quanta in ns, propagation segment, phase buffer
710 <http://www.mjmwired.net/kernel/Documentation/networking/can.txt#710>       
        segment
1 and 2 and the synchronisation jump width in units of
711 <http://www.mjmwired.net/kernel/Documentation/networking/can.txt#711>       
        tq.
They allow to define the CAN bit-timing in a hardware
712 <http://www.mjmwired.net/kernel/Documentation/networking/can.txt#712>       
        independent
format as proposed by the Bosch CAN 2.0 spec (see
713 <http://www.mjmwired.net/kernel/Documentation/networking/can.txt#713>       
        chapter
8 of http://www.semiconductors.bosch.de/pdf/can2spec.pdf).


Could I have something to precise after defining baudrate ?
