  I got Micky's patches from him, applied them to the source from lbl, grabbed
the nit_if.o module from lbl, rebuilt my kernel, remade tcpdump, and I now
have a version of tcpdump that works on my 3/50 running 4.0.1 (thanks, guys!)
I tried it out on a Sun-4, and it compiles and links fine but produces no
output. I assume that I need a fixed nit_if.o for a Sun-4. Anybody got one?
  The only nuisance is that the makefile for the tcpdump source references
a program called "flex" which is not a part of the Sun OS, so I had to grab
those sources from lbl as well and make that program before I could get
tcpdump to compile. A nuisance, but doable. Flex compiles without any trouble
on both the Sun-3 and Sun-4 (running OS 4.0.1)
  If anybody wants to avoid this procedure, I have the Sun-3 binary available
for anonymous FTP from ncar.ucar.edu (128.117.64.4), as pub/tcpdump.sun3.os4
You will need to remake your kernel with the nit_if.o from lbl before you
will be able to use this binary.
