Testing and bug fixes
- Testing of ML2 by everyone would be appreciated
- We need to find and fix any bugs in the next couple of weeks

Icehouse Design Summit Topic ideas
- RPC handling in ML2 for Type and Mechanism Drivers
- More extensible TypeDrivers for controller-based MechanismDrivers
- Monolithic Plugin vs. ML2 MechanismDriver - current and future plugins
- Future Directions for ML2 (orchestration, deployment, management, ...)
- Migration from deprecated Plugins (openvswitch, linuxbridge) to ML2 - automation?
- Add support for VXLAN multicast to the OVS agent with newer versions of OVS and Linux kernel.
- Multi-segment provider network implementations in MechanismDrivers, specifically OVS.
- Additional provider network attributes for controller-based plugins such as ODL for networks created outside of Neutron.

General ML2 Information

Here are the current ml2-specific blueprints for havana:

These tunnel-related blueprints effect the openvswitch and/or linuxbridge agents, and the features should also (or exclusively) be supported (using both agents simultaneously where applicable) by the ml2 plugin:

These blueprints involve the ml2 MechanismDriver API:
