The StarLAN driver wasn't written by me; it was written by Garrett Wollman
(wollman@trantor.emba.uvm.edu) at the University of Vermont.
Here is the posted information (Message-ID: <1992Aug11.174255.5756@uvm.edu>):

This is actually not the most recent posting, and the driver has been updated
to include a number of bug fixes by myself and the original author.
I was not given permission to include the driver in the patch kit; to be
fair, the patch kit makes it difficult to distribute README's or other
documentation not in "man" format, and no such documentation existed for
the driver; therefore credit wouldn't be very conspicuous. Also Garrett
felt that it was not releasable except as a beta as it was, although I
find the newer driver massively more stable (still has occasional crashes
with massive net loading -- for instance, start 5 ping -f's against
another box, and it will crash 386BSD pretty quickly).
If you get the driver from him, you can easily add more card types, since
the majority of the code is shared and what isn't is function vector
table driven; if you have documentation for the new card, adding it if it
uses the same chip set should be cake. I suspect that the AT&T StarLAN
fiber optic card would just need a type recognition field and could use
the same functions as the other AT&T cards.
