FreeBSD kernel module and sending udp packets

[Ferner Cilloniz]

Hi Julian. I'm very happy for your help. I have read the guide to
netgraph and find it very interesting :)

I still dont understand when you say "you could give your module a
netgraph interface."

Can you please explain this a little more please?

Thanks.
