This patch series tries to handle port binding, datapath binding
and ovs interface changes incrementally.
First 2 patches does some refactoring. Submitting this as RFC to get
some comments.
Still need to update the proper commit messages and fix one test case
related to Incremental processing which is failing. Another test case
related to Interconnection is failing.
Below are the results of some testing I did with ovn-fake-multinode
setup
Test setup
------
1. ovn-central fake node running OVN dbs and 2 compute nodes running
ovn-controller.
2. Before running the tests, used an existing OVN db with the below
resources
No of logical switches - 53
No of logical ports - 1256
No of logical routers - 9
No of logical router ports - 56
No of port groups - 152
No of logical flows - 45447
Port bindings on compute-1 - 19
Port bindings on compute-2 - 18
No of OF flows on compute-1 - 84996
No of OF flows on compute-2 - 84901
3. The test does the following
- Creates 2 logical switches (one for each compute node) and connect to a
logical router for each compute node.
- 100 logical ports are created (50 per lswitch), a simple ACL is added and
the address
set is created for each port.
- Each port is bound on the respective compute node and the test
pings the IP of the port (from another port belonging to the same
lswitch created earlier).
Below are the results with OVN master

Testing the same with fresh OVN dbs didn't show any improvements in the
timings.
v1 -> v2
---------
* Added 2 new patches
* Patch 5 (ofctrl_check_and_add_flow) was submitted earlier too and
the previous discussion is here - https://patchwork.ozlabs.org/patch/1202417/
* Patch 6 handles I-P for ct_zone and OVS interface changes in
flow_output_run stage.
Numan Siddique (6):
Refactor binding_run()to take two context argument - binding_ctx_in
and binding_ctx_out.
ovn-controller: Refactor binding.c
ovn-controller: I-P for port binding in runtime_data stage
ovn-controller: I-P for datapath binding
ofctrl_check_and_add_flow: Replace the actions of an existing flow if
actions have changed.
ovn-controller: I-P for ct zone and OVS interface changes
