It is an intelligent CAN PCI card. I'm pretty sure they're the card
described here: http://www.janz.de/as/en/can-cp6/k2.html

Since this driver is for passive cards, it clearly won't work. Are there
any examples of drivers written for intelligent CAN cards? Until I found
the website above, I'd never seen any data sheets for this card. They
look like they may have enough information to write a driver to
interface with the new Linux CAN layer.

We should probably start a new thread about this, it is getting
off-topic for Pavel's CAN driver. Is the socketcan mailing list ok for
this kind of discussion?

Thanks,
Ira
