[PATCH 2/2] app/testpmd: user assigned flow ID to flows

[Thomas Monjalon]

22/02/2023 15:11, Eli Britstein:
> Currently, testpmd assigns its own IDs, as indices, to created flows.
> Later, the flow index is used as the ID for flow operations (query,
> destroy, dump).
> 
> Allow the user to assign a user-id, to be later used as an alternative
> to the flow index testpmd assigns.
> 
> Example:
> 
> testpmd> flow create 0 ingress user_id 0x1234 pattern eth / end actions
> count / drop / end
> Flow rule #0 created, user-id 0x1234
> 
> testpmd> flow query 0 0x1234 count user_id
> 
> testpmd> flow dump 0 user_id rule 0x1234
> 
> testpmd> flow destroy 0 rule 0x1234 user_id
> Flow rule user_id 0x1234 destroyed
> 
> testpmd> flow destroy 0 rule 0x1234 user_id
> Flow rule #0 destroyed, user-id 0x1234

Please Eli, we need explain why adding this feature.
Could you add the justification done in the RFC?
Thank you.
