Hi,

Suppose we want to collect per-port IPFIX statistics in an OVN-managed virtual network.

Looks like the most straightforward way to do this is to add a Flow_Sample_Collector_Set entry and a flow with sample() action to match the given port (think physical one, for simplicity).

However, I'm not sure which table should one add this flow in the OVN pipeline. Does the pipeline account for such use case at all? I feel it misses something like "user-defined action" set of tables both for ingress or egress traffic. Integrating all of this with OVN controller to match on logical ports could be even better idea.

Is my understanding correct, or am I missing something?
