It's been experimental for some time. The project struggles with a matrix of configurations, obsolete docs etc. It's better to remove code than let it rot. Interested parties are recommended to migrate to a supported driver (preferrably the default driver for neutron - OVN), or take over maintenance of the linuxbridge driver out-of-tree.

Networking service overview
OpenStack Networking (neutron) allows you to create and attach interface devices managed by other OpenStack services to networks. Plug-ins can be implemented to accommodate different networking equipment and software, providing flexibility to OpenStack architecture and deployment.
It includes the following components:
- neutron-server
-
Accepts and routes API requests to the appropriate OpenStack Networking plug-in for action.
- OpenStack Networking plug-ins and agents
-
Plug and unplug ports, create networks or subnets, and provide IP addressing. These plug-ins and agents differ depending on the vendor and technologies used in the particular cloud. OpenStack Networking ships with plug-ins and agents for Open vSwitch and Open Virtual Network (OVN), as well as for SR-IOV and Macvtap.
The common agents are L3 (layer 3), DHCP (dynamic host IP addressing), and a plug-in agent.
- Messaging queue
-
Used by most OpenStack Networking installations to route information between the neutron-server and various agents. Also acts as a database to store networking state for particular plug-ins.
OpenStack Networking mainly interacts with OpenStack Compute to provide networks and connectivity for its instances.
