    You are not missing anything but a consensus was reached and I am not willing to reopen the issue.
    You may choose to support errorlevel=1.

    Just a quick note. Some people have implied that the
    use of A-bit necessarily means poor performance.

    I would like to disagree. If the target is just
    sitting there waiting for acknowledgment to come
    back before sending the next Data-In sequence, then
    yes, that's poor performance. But I can imagine
    targets that keep sending data while waiting for
    the outstanding acknowledgments. Yes, it requires
    more buffer space, but the acknowledgments are
    actually helpful in managing that bigger buffer space.
    It's a very similar situation to multiple outstanding
    R2T-s. Hopefully everybody agrees that there may be
    benefits to those.

    Or am I just missing something again?
