[ovs-discuss] OVS Queues min rate not maintained

Okay I dug a little deeper in htb queues and I have realized that my
concept was a little messed up. What I thought was if we send packets at a
rate less than that of the minimum rate the egress queue should either stop
it or increase it to its minimum specified rate.
But thats not the case.
