Hi Numan,

Looking at this series, I realize that this section of the OVN code is not exactly my wheelhouse. While I don't spot anything obviously incorrect (e.g. memory leaks, failing tests), I think to properly give this the scrutiny it needs, it would require me to study the code again to ensure I understand all the ins and outs. I will do this in my free time so that I can give better reviews in the future, but for now in the interest of expediency, I will put:

I'm going to unassign myself from this review so that someone else can give a better review.

This patch series attempts to improve the handling of runtime_data
changes in the engine nodes - ct_zones and pflow_output.
It also attempts to improve the handling of ct_zones change in
pflow_output engine.


After this patch series,  the amount of full recomputes of pflow_output
engine is reduced drastically.  This helps in scaled environments.

For example with the simple ovn-scale-test which creates 20 logical
ports (10 each in one logical switch) and binds it equally on two chassis,
reduces the number of physical_run() calls from around 30 to around 8.

   * Rebased to resolve the conflct.

Numan Siddique (5):
   controller: Move 'struct local_datapath' to a separate file.
   binding: Add the localport port binding in the binding_lport
     information.
   binding: Track the changes of container lport when it's parent
     changes.
   I-P: Handle runtime data changes for plow_output engine.
   controller: Improve ct zone handling.
