Great, *you* handle the whole thing". I've very much weary of putting a second TCP stack in userspace for the same reasons most folks are weary of TOE. And frankly we should only go towards that kind of duplication if it shows a real performance gain. Nevertheless I do highly encourage folks to experiment with that as much as possible, I could be dead wrong on my hunch that it won't help enough to justify allowing it. - To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
