Thank you all for a constructive discussion at the Shanghai PTG. First
of all I want to clarify that the Neutron improvements in bulk port
creation code I talked about were only merged in Stein and are not
available in Queens. Sorry about that, my mistake.

Below I want to list some highlights from the discussion.

 * There seemed no pushback on switching to independent release model,
   so I'll follow up on that soon.
 * We discussed using RPC instead of API polling to detect when port
   becomes ACTIVE in Neutron (https://review.opendev.org/#/c/669642/).
   I commented on the review with a follow up that came from discussion
   with Neutron team. Apparently there are 2 better ways of doing this.
   Let's continue that discussion on the review.
 * We know that we don't support running as a second CNI plugin on
   Multus because of eth0 being hardcoded as interface name and kuryr-
   controller handling pods that do not had CNI requests. This is
   something to solve.
 * Apparently we all suffer the same problems with Neutron performance
   when starting a bigger workload on Kuryr-configured K8s cluster
   (think big Helm chart, multiple operators or simultaneous test
   suite). This all comes to reducing the number of calls to Neutron.
   We still don't see a feasible solution to solve this problem, but it
   seems to be a priority for both Samsung and Red Hat at the moment.

Let's see if we'll meet again in Vancouver!
