Dear friends,
Please excuse-me for not reporting earlier... I confirm that the patch by
Michael really fixes the problem I've reported. The regression has gone away
when I used it, so I think it is good to be applied.
Thanks,

Commit 0d8d7690850eb0cf2b2b60933cf47669a6b6f18f introduced

To fix, add parameters limiting lookahead, and
use in virtqueue_avail_bytes.
