[ovs-dev] [PATCH ovn 0/3] controller: Notify when an OVN port is ready to use.

[Dumitru Ceara]

This series adds support to ovn-controller to notify northd that all OVS
flows and OVS interface corresponding to an OVN logical port have been
installed in OVS.

The series extends the ofctrl barrier implementation and makes it generic
so that multiple modules can use it.  For now these are:
- main ovn-controller for nb_cfg propagation.
- binding module for marking Port_Bindings as installed.

NOTE: With these patches applied one of the unit tests fails more often.
A separate patch has been submitted for that:

Dumitru Ceara (3):
      ofctrl: Rename 'nb_cfg' to 'req_cfg'.
      controller: Implement a generic barrier based on ofctrl cur_cfg sync.
      binding: Set Logical_Switch_Port.up when all OVS flows are installed.
