Correction/clarification: call tomorrow is about
multiple-cluster-networks, and it was a bad idea on my part to try to
hijack that with neutron-ml2 discussion. Lets not do that and continue
discussing the blueprint spec in gerrit, and hopefully by Thursday
Andrew will have enough code out there to make the discussion more
concrete. Link:
