[Bug 2032770] Re: [SRU] [OVN] port creation with --enable-uplink-status-propagation does not work with OVN mechanism driver

[Mustafa Kemal Gilor]

Hello Julian,

I'm unsure what you mean by "as the patches *are* *still* UNRELEASED;",
I've re-checked all the patches and only one of them (jammy) mistakenly
had the "UNRELEASED;" as the series name -- which I've corrected and re-
submitted. Please let me know if I'm doing something incorrectly, or if
anything else needs correction for that matter.

Regarding the OpenStack pockets, Corey is already handling that side
(btw, thanks Corey!).

Bug description:
  [Impact]

  This SRU is a backport of
  https://review.opendev.org/c/openstack/neutron/+/892895 to the
  respective Ubuntu and UCA releases. The patch is merged to all
  respective upstream branches (master &
  stable/[u,v,w,x,y,z,2023.1(a)]).

  This SRU intends to add the missing 'uplink-status-propagation'
  extension to ML2/OVN. This extension is already present and working in
  ML2/OVS, and it is supported by ML2/OVN but the extension is somehow
  not added to ML2/OVN. The patch simply adds the missing extension to
  the ML2/OVN too.

  The impact of this is visible for the deployments migrating from
  ML2/OVS to ML2/OVN. The following command fails to work on ML2/OVN:

  ```
  openstack port create --network 8d30fb08-2c6a-42fd-98c4-223d345c8c4f --binding-profile trusted=true --enable-uplink-status-propagation --vnic-type direct aaa

  # BadRequestException: 400: Client Error for url:
  https://mycloud.example.com:9696/v2.0/ports, Unrecognized attribute(s)
  'propagate_uplink_status'

  ```

  The fix corrects this behavior by adding the missing extension.

  [Test Case]

  - Deploy a Focal/Yoga cloud:
      - ./generate-bundle.sh -s focal -r yoga --name test-focal-yoga-stack --run --ovn
      # After the dust settles
      - ./configure
      - source ./novarc
  - openstack port create --network <network-id> --binding-profile trusted=true --enable-uplink-status-propagation --vnic-type direct aaa
  - It should fail with "BadRequestException: 400: Client Error for url: https://mycloud.example.com:9696/v2.0/ports, Unrecognized attribute(s) 'propagate_uplink_status'"

  To confirm the fix, repeat the scenario and observe that the error
  disappears and port creation succeeds.

  [Regression Potential]
  The patch is quite trivial and should not affect any deployment negatively. The extension is optional and disabled by default.
