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.

L2 Agent Extensions
L2 agent extensions are part of a generalized L2/L3 extension
framework. See agent extensions <agent_extensions>.
Open vSwitch agent API
- neutron.plugins.ml2.drivers.openvswitch.agent.ovs_agent_extension_api
Open vSwitch agent API object includes two methods that return wrapped and hardened bridge objects with cookie values allocated for calling extensions:
#. request_int_br
#. request_tun_br
Bridge objects returned by those methods already have new default cookie values allocated for extension flows. All flow management methods (add_flow, mod_flow, ...) enforce those allocated cookies.
