As a note: The newly added system test sometimes fails as it is finding some warnings in the controller.log (e.g. 2023-04-19T13:18:29.536Z|00087|if_status|WARN|Trying to release unknown interface lsp1)
This can happen in the following scenario: - logical port is created - OVS interfaces is added w/ iface-id - Port is claimed, setting pb->chassis in SB. SB very slow - Removing OVS interfaces - iface deleted in if-status (if_status_mgr_release_iface destroying the iface in CLAIMED state) - pb->chassis update received from sb => port released, iface released from iface-status This issue existed before this patch and has been fixed in the next patch.
