If you are sure you REALLY want the rate that tc is complaining about,
you should manually set quantum, probably to 1514 (look at quantum for a
rate that does not generate this message for size hints). htb is
telling you that the rate is a lot less than the rate of the parent;
experience says 31% or less of the parent rate generates this message.
tc class add dev eth1 parent 1:1 classid 1:30 htb rate $RATE ceil $CEIL
burst 5k quantum 1514 prio 3
