What would you like to see implemented?
Create a controller to manage neutron QoS, and update the existing networking controllers that can make use of it (Ports in particular).
Additional information
There's demand for it in CAPO, see discussion in kubernetes-sigs/cluster-api-provider-openstack#2800.
