One typical use case for TBF is you talking to a DSL bridge that is connected using a GBit Ethernet switch. For these DSL connections it gives much better behaviour to shape the traffic to slightly below your external link speed so that you can e.g. prioritize packets properly. But the actual external link speed is much lower than GbE. A lot of GbE NICs enable TSO by default. -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
