Thanks a lot for working on this!  My understanding is that the metadata
API support, added to the DNS support that Numan Siddique is building,
will complete OVN's basic OpenStack support, which will be great to
have.

Before I review this patch in detail, can you help me to understand what
other components, in OVN or in Neutron, will be needed to make the
overall metadata API feature work?  Is it just a matter of plugging a
bit into the Neutron networking-ovn driver, or do we need additional
infrastructure in OVN beyond this patch?  I'm trying to understand the
full context here.

Thanks,

Ben.
