    The patch is attached. It's rather small, and it has been
    tested on the IFCAP_VLAN_HWTAGGING hardware. It should now
    be faster than ever.

    The first argument to VLAN_OUTPUT_TAG() is now unused, but
    I don't think it would be a good idea (though I'm not opposed
    to it either) to trim it.

    I also embellished a fix in rev. 1.174 of if_ethersubr.c -- it
    now properly checks for mbufs with VLAN tags, making it possible
    to bridge(4) on vlan(4)'s whose parent interfaces support VLAN
    decapsulation in hardware.

    Cheers,
