Re: hwvtep high level control flow

sounds good. i will add it in the workflow and send out before the meeting.
for #1, i can add a workflow for hwvtep-hwvtep tunnels, however, it does not really fit in with the gateway model. but technically, should be supported.
for #2, i have hinted at this scenario where switch initiates the connection on slide 1 bullet 2. basically, if the switch has already actively connected to the controller, the controller needs to co-relate an l2-gw create operation with an existing node. in this case, we need to use some mechanism to co-relate the device id received from the api with a node, so my question to the community would be - can we ensure device_id is set to switch name in the NB, and we use this to co-relate?
ravi, is there some other mechanism used in the openstack version of l2gw today?

It's good to add md-sal data store in between, because in beryllium release neutron-northbound project won't be talking to net-virt directly. Neutron northbound will be pushing all the data to data store and net-virt will be listening to those data changes.
As of now Net-Virt relies that use will connect the compute nodes to the controller using tcp:ip:port, rather then putting switch in passive mode (ptcp:port) and expected controller to connect to it. Although OVSDB southbound plugin allows user to proactively connect to the switch if switch is listening for the connection by putting hyper-visor data in config data store. If OpenStack l2gateway rest APIs provide hardware vtep device information (ip,port this device is listening for connection on) then i think you can support controller initiated connection as well.
