[En-Nut-Discussion] RFC: can_dev.c proposed changes

Right,

Good point. I think a hardware specific filter setting is the best 
compromise.

I also don't have a problem with overwriring can_set_filter with the new 
Code. Is anybody out there whom it would concern? Otherwise we should 
mark this function deprecated and remove it later.

Bye,

Ole Reinhardt
