Some time ago, Mike Petry and I wrote a driver for this part for NetBSD (me)
and BSDI (Petry). See
http://www.TransSys.COM/TransSys/NetBSD/znet.html
for the NetBSD driver. Note this is pretty old, and probably doesn't
drop into anyone's kernel these days.
This was for a Zenith Z-Note laptop (with a 486SL CPU!). It worked
quite well, and I recall running tcpdump fairly effectively.
I've started porting it to FreeBSD a couple of times, but I fear the
code is cursed; each time I started converting the driver, some horrible
disaster would befall my system, and the disk with the code in progress
would die a horrible death. You have been warned :-)
I know that I have the Intel databook for this part *somewhere*, but I
haven't seen it since I moved a year and a half ago. I think you'll get
quite a head starting with the NetBSD driver, though. The driver is a
little grotty in the sense that it's an 82593 driver for the Zenith laptop
and it needs to do some rather rude DMA controller setup because of the
way the 82593 works. Take a look at the code; you'll see.
