need NIT help for our netwatchtool on SunOS 4.0

[Tom Dunigan 576-2522]

We have converted the NIT stuff for our netwatchtool from 3.5 to 4.0, but
the promiscuous packets returned are mostly "truncated" (just the NIT
header stuff and about 16 bytes of the Ether packet).  snaplen is 92,
running in nbuf mode, i don't have Sun sources (presumably a peek at
rpc.etherd would answer my questions).

any suggestions or incantations?

thanks
