Efficient Networks, and the Adaptec equivalents.

PVCs.  Basically, you can add static routes to hosts via link routes.

A couple of years ago, I was doing some work with ATM and NetBSD, but
ATM has fallen out of favor here, so I'm no longer doing any work on it.

However, with the new ARP framework we have, doing Classical IP over ATM
(i.e. with ATMARP) should be much easier than it was when I started working
on it :-)

Well, there's no need for that.  I know of an ISP that is using NetBSD
and an Adaptec ATM card to connect themselves to a city-wide backbone,
and last I heard, he was getting reasonable performance.

Someone (Matthias Drochner, I think?) had a driver for the OPPO at one
point, but I don't know the status of the code.
