np100 ethernet processor on BSD4.3

[Phil Nelson]

(I'm posting this for a friend.  Please respond to scott at wwu.edu on CS-NET.)

I would like any hints or sources of information on configuring and using
the MICOM-Interlan NP100 Ethernet Protocol Processor.  I am working from
a BSD4.3 tape dated 6/7/86.  I have found the /np100 directory in the user
contributed library.  The if_ix.c and np.c files are dated June 5, 1986.  The
np.image file is dated Feb 10, 1986 and the npcmd.c, npdump.c and npload.c
files are dated Feb 20, 1986.  Are these the latest files?  Which is the
driver to use -- np.c or if_ix.c?  Section (4) has an ix and an np entry,
both of which say "device np0 ..." and then both go on to say to start the
device you say "# ifconfig ix0 ..." -- what is going on here?  What does it
take in the /sys/conf files devices.vax, files.vax, files to make this all
work as a protocol processor? Or is it both depending on drivers used and 
ifconfig's performed?  The target machine is a VAX/780.  Thank you in advance
for any help or direction.
