HTB will try to give each class it's rate as a minimum :
./tc class add dev lo parent 1:2 classid 1:10 htb rate 300kbps ceil 800kbps
prio 0
./tc class add dev lo parent 1:2 classid 1:11 htb rate 100kbps ceil 800kbps
prio 1
So class 1:10 gets 300kbps and class 1:11 gets 100kbps. The other 400kbps
will go to class 1:10 beacause his prio is lower. So prio is for traffic
that's left after each class gets his rate.
I hope I'm right, Devik ? :)
