FYI: I don't know if you have them or not, but a long time ago I
stashed away copies of the TC9020/TC9021 programming manuals. The
provenance of these parts is a little murky. I first learned of them
as being Sundance Technologies devices, but later I found references to
them belonging to a company called Tamarack M.I. Later still, a
company called ICplus ended up with them. ICplus eventually produced
a single chip device combining the TC902x MAC with an integrated PHY
(though I've yet to actually see a NIC that uses these anywhere).

Sundance and Tamarack seem to have disappeared, but ICplus is still
around (www.icplus.com.tw) and they still have the gigE MAC and PHY
manuals online. They deleted the original TC902x manuals from their site,
but I saved copies. :) I put all the manuals I have for these devices at
http://www.freebsd.org/~wpaul/Sundance along with the original ST201
manual. Note that I didn't have to sign any NDAs to get any of these.

In case you can't tell, the hardware API for the ST201 and the TC902x
is copied very closely from the 3Com 3c90xB/3c90xC devices.

Anyway, I'm posting these in case they help with maintaining the driver
(or if anyone just wants to tinker around with the hardware). Share
and enjoy!
