Re: Which CAN driver to port to for PPC

I know. When I started the project there only was one driver, and
it was already very complex. But it lacked the select method(now
poll), and had other serious design problems. So I started mine,
without advertising it.

Now I have a few happy users, and they want to keep my API in their
applications, so I'm stuck with it.

True, but the chip isn't _that_ different, actually.

Yes, that is how things should be, in an ideal world.

It would. Anyone willing to lead this effort? [no offence or humor
intended, I am interested in following it, but can't lead it myself]
