    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.
