    Ok. Maybe we're getting somewhere here ... or at least I am :-)

    I'm not trying to be pedantic here but let me try and restate what I
    think you said above:

    - The "header" traverses the real networking stack
    - The "payload" is placed either by by the hardware if possible or by
    the native stack if on the exception path
    - The "header" may aggregate multiple PDU (RSO)
    - Data ready indications are controlled entirely by the software/real
    networking stack
