By "IP module" do you mean an Industry-Pack module, or some device that
connects between a CANbus and regular network port? I suspect you're
using the latter, but my Tip810 driver that you found can only talk to
this specific Industry-Pack module:

If you *are* using Industry-Pack, what kind of carrier board do you have
the module installed on?
I'll be happy to write more after you've confirmed the above.

Arguing for surveillance because you have nothing to hide is no
different than making the claim, "I don't care about freedom of
