What is the status of the flavor framework? Is this the right spec? https://blueprints.launchpad.net/neutron/+spec/neutron-flavor-framework I'm trying to sort through how the ML3 proposal https://review.openstack.org/#/c/105078/ fits in with requirements for high performance (high throughput, high packets per second, low latency) needed for workloads like VoIP, video and other NFV functions. It seems to be the consensus that a significant part of the intent of ML3 is "flavors for routers" and that makes it natural that ML3 should have a dependency on flavor framework but the blueprint referenced above doesn't have a series or milestone target.
