Well I have contributed the AT90CAN driver this is correct, but the 
driver is modelled after the SJA1000 driver so it can plug into Ole 
Reinhard's dev/can_dev.c API. Not sure if the STM CAN drivers can be 
plugged into the can_dev API and if that would even make sense.

I found with CAN applications it easier to use directly the low level 
driver so I can best make use of the particular functions of the 
controller. Like filtering and message queue management and timing 
control. All these are hard to accomplish with a one-fits-all API.

But this discussion is probably worth a new topic.
