Hm - i wrote that some days ago:
The CAN netdev driver model is as easy and simple as ethernet devices.
To fulfill multi-user requirements the CAN driver disables any CAN controller
specific filters and mailboxes to enable all different users on the host to
filter their own requires messages, using the CAN filter infrastructure:

You can also check out the filter capabilities with the 'candump' tool, see
'candump -?'
Does this help?

Oliver
