classification priomap that sch_prio uses, so it should be intuitive to
configure for people who've used sch_prio.
The PRIO qdisc naturally plugs into a multiqueue device. If PRIO has been
built with NET_SCH_PRIO_MQ, then upon load, it will make sure the number of
bands requested is equal to the number of queues on the hardware. If they
In order to utilitize the multiqueue features of the qdiscs, the network
device layer needs to enable multiple queue support. This can be done by
selecting NETDEVICES_MULTIQUEUE under Drivers.
The PRIO qdisc naturally plugs into a multiqueue device. If
NETDEVICES_MULTIQUEUE is selected, then on qdisc load, the number of
bands requested is compared to the number of queues on the hardware. If they
are equal, it sets a one-to-one mapping up between the queues and bands. If
they're not equal, it will not load the qdisc. This is the same behavior
for RR. Once the association is made, any skb that is classified will have
