Worked a bit on the 'ep' driver this weekend. Cleaned up a bunch of stuff and mostly used good ideas from the NetBSD 'elink3' driver backend.
Of course the damn 3C1 still doesn't work. *sigh* I suspect its some weird link setting that I'm not getting so I'll have to re-read the documentation (such as it is) and see if I can figure it out.
I still haven't sorted out the rest of the dev boxes.
