Since the conversation reported in [1], the information to be reported
to Nova will not be stored in the port "resource_request" and the
NUMA affinity policies will not be considered as resource provider
traits.
NUMA is going to be modeled in Placement soon, but until this feature
does not land in a stable version, Neutron will only provide this
information via an extension.
