Modular L2 MechanismDriver API

Registered by Robert Kukura on 2013-06-03

The MechanismDriver API and associated MechanismManager class are just stubs in the current ml2 implementation. These both need to be extended to support integration with external devices such as SDN controllers and top-of-rack switches. MechanismDrivers need to be called as part of CRUD operations on the network and port resources, both within the DB transaction and after the DB transaction commits. Involvement of MechanismDrivers in port binding (plugging) is being addressed in https://blueprints.launchpad.net/quantum/+spec/ml2-portbinding.

The relationship between this BP and https://blueprints.launchpad.net/quantum/+spec/ovsplugin-hardware-devices must be determined. One approach is to ensure the HardwareDriverAPI can be implemented in terms of ml2's MechanismDriver API, the other is to simply use the MechanismDriver API in place of the HardwareDriverAPI.
