I've fixed a bug which resulted in checksum offload bug and update the
patch. It should have no ression.
We're very close to code freeze and have too many consumers of re(4).
Without users success report it would be impossible to commit the patch
before branching 7. Since I don't have 8139C+ based ones, I'm also
interested in how it works on 8139C+ hardwares.
