Our lab has finished testing these patches.  The patches work in the
sense that no oversize packets are now passed to the driver with the
patches applied.  But I'm not seeing these bad packets reaching the
blackhole device and getting dropped there.  So they get dropped in
some other code paths.  I believe we saw the same results with your
earlier patches.

Thanks.
