Sure, by adding yet another queue and extra latencies. If the switch delivered a high prio packet to your host right before a train of 60 low prio packets, this is not to allow us to wait the end of the train. We have to really invent something better, like a real pipeline, instead of hacks like this, adding complexity everywhere. Have you tested this on cpus with tiny caches, like 32KB ?
