Are you intending to have this hook into the normal FreeBSD TCP/IP
stack or be truly standalone? I read your question as the latter but
others seem to read it as the former.
If the latter, I'd suggest splitting it up into several netgraph
nodes, eg.:
| | | | | |
ng_udp ng_tcp
\ /
\ /
ng_ip
|
|
ng_arp
| |
| |
ng_ether
