    Oooh.  Very nice.  And I happen to have test boxes with nVidia chipsets
    that the driver recognizes!

    I got an assertion when I tried to ifconfig it up.  I think the issue
    is simply that the serializer has already been acquired when nfe_jalloc()
    or nfe_jfree() are called (since you also specified it when you
    installed the interrupt vector).  If I remove the serializer calls
    from those two routines I can ifconfig it up.
