One more thing to add is that the BPF code you are looking at is part of
the support that allows certain well behaved oskit kernels to be run as a
usermode process. Netios are mapped into the BPF device of the host system
(freebsd, linux). So, its not really going to help you out.

Look at the stuff that Mike mentioned above.
