I write my device drivers from datasheet information, without reference to
other device drivers (e.g. from *BSD). Exceptions and other sources of
information (e.g. during 1992-1994 the GPLed Crynwr drivers were the only
documentation for some boards) are noted in the driver.
The FreeBSD EPIC/100 driver
ftp://ftp.FreeBSD.ORG/pub/FreeBSD/FreeBSD-current/src/sys/pci/smc83c170.h
is substantially similar to my source code because they used parts of my
Linux driver (without attribution), not the other way around.
Similarly I was recently made aware of a driver named 'if_zn.c' for *BSD
which is my znet.c driver converted to a BSD interface, again without
permission or attribution and in violation of the copyright.
