In the current approach QoS support is being "hardwired" into ML2.

Maybe this is not the best way of doing that, as perhaps it will end up
requiring every mech driver which enforces VIF configuration should support
I see two routes. One is a mechanism driver similar to l2-pop, and then you
might have a look at the proposed extension framework (and partecipate into
the discussion).
The other is doing a service plugin. Still, we'll have to solve how to
implement the "binding" between a port/network and the QoS entity. If we go
for the approach we've chosen so far the resource extension model you still
have to deal with ML2 extensions. But I like orthogonality in services, and
QoS is a service to me.
Another arguable point is that we might want to reconsider our
abuse^H^H^H^H^H use of resource attribute extension, but this is a story
for a different thread.

Regarding the incubator request, I think we need to wait for the process to
be "blessed". But you have my support and I would happy to help to assist
with this work item through its process towards graduation.

This obviously provided the QoS team wants me to do that!
