General ML2 Information

Here are the current ml2-specific blueprints for havana:

• https://blueprints.launchpad.net/quantum/+spec/ml2-gre
• https://blueprints.launchpad.net/quantum/+spec/ml2-mechanism-drivers
• https://blueprints.launchpad.net/quantum/+spec/ml2-portbinding
• https://blueprints.launchpad.net/quantum/+spec/ml2-vxlan
• https://blueprints.launchpad.net/quantum/+spec/ml2-multi-segment-api

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:

• https://blueprints.launchpad.net/quantum/+spec/ovs-vxlan-lisp-tunnel
• https://blueprints.launchpad.net/quantum/+spec/openvswitch-kernel-vxlan
• https://blueprints.launchpad.net/quantum/+spec/vxlan-linuxbridge
• https://blueprints.launchpad.net/quantum/+spec/ovs-tunnel-partial-mesh
• https://blueprints.launchpad.net/quantum/+spec/l2-population

These blueprints involve the ml2 MechanismDriver API:

• https://blueprints.launchpad.net/quantum/+spec/tailf-ncs
• https://blueprints.launchpad.net/quantum/+spec/ovsplugin-hardware-devices
