  # That value needs to map to the actual host name specified in Upshift. If you
  # supply an override to the hostname through role data, you need to update this

It appears that the following change doesn't include the necessary changes for the interface name refactoring:

Reason: https://review.opendev.org/#/c/751720/ I think addressed this. It left master broken for about a day since it landed so much later than the first

    Replace bridge_name and interface_name in config

    The new ansible os_net_config does not replace the interface_name
    and bridge_name variables in net config. This replaces those
    variables beforehand.

    Though it would have been good to handle it in module itself, in
    the proposed way to generate these configs with ansible would
    allow us to replace them with group_vars.
