Hello all,

I am trying to raise the priority of VoIP traffic, and am able to get it into
the appropriate PRIO bands like so:

	 /sbin/tc qdisc add dev eth0 root handle 2: prio bands 3 priomap 0 1 2
	 /sbin/tc qdisc add dev eth0 parent 2:1 handle 3: sfq
	 /sbin/tc qdisc add dev eth0 parent 2:2 handle 4: sfq
	 /sbin/tc qdisc add dev eth0 parent 2:3 handle 5: sfq

	 /sbin/tc filter add dev eth0 parent 2: protocol ip prio 1 \
			u32 match ip dst 10.0.0.20 flowid 2:1
	 /sbin/tc filter add dev eth0 parent 2: protocol ip prio 2 \
			u32 match ip dst 10.0.0.2 flowid 2:2
	 /sbin/tc filter add dev eth0 parent 2: protocol ip prio 2 \
			u32 match ip dst 0.0.0.0/0 flowid 2:0

However when I try to encapsulate the prio qdisc (see below), tc status
reports that none of the packets are going into the bands. What am I missing?

		tc qdisc add dev $DEV root handle 1: cbq avpkt 1000 bandwidth 10mbit

# shape everything at $UPLINK speed - this prevents huge queues in your
#	DSL modem which destroy latency:
#	main class

		tc class add dev $DEV parent 1: classid 1:1 cbq rate ${UPLINK}kbit \
			allot 1500 prio 5 bounded isolated

		tc qdisc add dev $DEV parent 1:1 handle 2: prio bands 3 priomap 0 1 2

		tc qdisc add dev $DEV parent 2:1 handle 3: sfq
		tc qdisc add dev $DEV parent 2:2 handle 4: sfq
		tc qdisc add dev $DEV parent 2:3 handle 5: sfq

		tc filter add dev $DEV parent 2: protocol ip prio 1 \
			u32 match ip dst 10.0.0.20 flowid 2:1
		tc filter add dev $DEV parent 2: protocol ip prio 2 \
			u32 match ip dst 10.0.0.2 flowid 2:2
		tc filter add dev $DEV parent 2: protocol ip prio 3 \
			u32 match ip dst 0.0.0.0/0 flowid 2:3
