Thats essentially what i am arguing for. [I think some, not all, of the wireless qos schemes also have similar scheduling]. My understanding of these wired "datacentre/virtualization" schemes you describe is they are strict prio based. When the low prio "virtual wire" is contending for the "physical wire" with a higher prio "virtual wire", the high prio always wins. We just need to make sure this behavior is also maintained whatever buffering scheme is used within or above the driver(qdisc level). cheers, jamal -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
