I am writing a network monitor for a Sun 3/110 running SunOS 4.0.  I have
it grabbing packets off the net, but a good chunk of them get dropped.
Because of this I thought I would use NIT packet filtering.  Well, I have
read the man pages, looked throug the header files, and experimented quite
a bit, but with no luck.  Can someone out there help me.  Possible with an
exaple that filters out packet not matching a particular ethernet address,
or someting else that is longer that 2 bytes. 

	Thanks in advance,
