Julian> netgraph interception?

I don't understand the question.  If you have a vlan on nge0, and you
tcpdump the vlan interface, you get what you expect.  If you tcpdump
the nge0 interface, you get all the packets from all the vlans without
vlan tags to differentiate.  The FreeBSD and Linux drivers share this
behaviour.

Dave.
