Neutron QOS does not work with fraction RX_TX flavor value

[Raghu Katti]

We have noticed this in Icehouse. Neutron QOS queue does not get created with scaled max value when the RX_TX value of nova flavor is a fraction e.x. 0.5 or 1.5

It worked correctly when we tested with RX_TX value of 5.0. Here we saw neutron queue got created with max value of 5120, since the queue value that was attached to network is 1024.

However for fraction values of flavor the neutron queue max value stayed the same at 1024. To reproduce :

1. Create flavors with appropriate flavor

2. Create neutron queue with 1024 max value

3. Create network with queue id for earlier neutron queue

4. Spin VMs with appropriate flavor

5. Run neutron queue-list on controller. Check for max value.

My apologies I did not notice your bug report as it was targeting neutron rather than vmware-nsx and I filed another one as this was discovered independently in internal testing
