My point was that without TSO different submitters will interleave their streams (because they compete about the qdisc submission) and then you end up with a smooth rate over time for all of them. If you submit in large chunks only (as TSO does) it will always be more bursty and that works against the TBF goal. For a single submitter you would be correct. -Andi -- 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
