where are your packets supposed to come from?

I think I asked you this before so sorry if you answered
it and I have forgotten.

i.e. what is in them?



start with /usr/src/sys/netgraph/ng_sample.c and ng_source.c

and make a nolde that generates teh packets you want to send,
and then attach it to an ng_ksocket node.. end of job
