OK I'll take a stab at writing a spec for this either tonight or
tomorrow. We'll deprecate the proxy APIs for os-attach-interfaces show
and list methods. We'll need to take into account that the create
(attach interface) action uses the show method which proxies to
neutron's show_port method, but I think we will have enough information
to avoid that proxy (that could probably just be a separate bug fix
As for os-virtual-interfaces, I don't plan on deprecating that, and
actually plan on enhancing it with a microversion in Ocata to return the
vif tags from the model (useful for microversion 2.32). Plus we'll be
able to use that for both nova-net and neutron since the data isn't
proxied from anywhere, it just comes from the nova DB.
