You might look at eg. the if_ed code to see how this is done; the core code is pretty frightening, but the bus attachments themselves are fairly straightforward. I'd suggest that you have a look at this first and see what you think, then get back to us. If you're interested in attacking it, the job isn't very hard and I don't know of anyone else working on it, so it'd be quite the valuable thing to do. -- \\ Give a man a fish, and you feed him for a day. \\ Mike Smith \\ Tell him he should learn how to fish himself, \\ msmith@freebsd.org \\ and he'll hate you for a lifetime. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
