I might get in trouble for posting this, but IBM themselves have the answer.
We needed to be able to write directly to ethernet (so we could communicate
with a PDP-11 running RSTS 9.6 - no TCP or IP available  :-(  ).  We kept
pounding our SE (in a FRIENDLY, persistent manner), telling him we had no
alternative (which was true).  

After six weeks, we were put in contact with someone in Texas (who I
cannot betray under penalty of death!), who provided us with a file called
bio_dd.h, along with example programs on how to read and write to the
ethernet.  

Out of respect for IBM, see your SE and have him get you that .h file.
I know it exists - I've seen it.  Good luck...
