Subject: Capture packets before kernel process
To: freebsd-net@freebsd.org

Hi!
I need some help, currently I'm working in a project where I
want to capture and process some network packets before the
kernel. I have searched but I have found nothing.
Is there some way to capture the packets before the kernel
?
You want to wedge your code to the if_input routine. Then pass the mbuf
to the original if_input routine.
there is a netgraph hook there.
man netgraph
