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. Thanks. -- Regards, Pyun YongHyeon
