Public bug reported: Change I07c70db027f2ae03ffb5a95072e019e8a5fdc411 made it so PRECOMMIT_DELETE and AFTER_DELETE both receive the network dict fetched from the DB (decorated with any resource_extend hooks). However, this network representation does not include segment information like segmentation_id or network_type.
The networking-generic-switch ML2 plugin assumes that such information is present on the delete postcommit hook and needs it to do its job: https://opendev.org/openstack/networking-generic- switch/src/branch/master/networking_generic_switch/generic_switch_mech.py#L164-L166 As a result networking-generic-switch cannot currently be deployed.
