> Subject: [PATCH v2 00/10] ethdev: datapath-focused flow rules management
>
> Three major changes to a generic RTE Flow API were implemented in order to
> speed up flow rule insertion/destruction and adapt the API to the needs of a
> datapath-focused flow rules management applications:
>
> 1. Pre-configuration hints.
> Application may give us some hints on what type of resources are needed.
> Introduce the configuration routine to prepare all the needed resources
> inside a
> PMD/HW before any flow rules are created at the init stage.
>
> 2. Flow grouping using templates.
> Use the knowledge about which flow rules are to be used in an application and
> prepare item and action templates for them in advance. Group flow rules with
> common patterns and actions together for better resource management.
>
> 3. Queue-based flow management.
> Perform flow rule insertion/destruction asynchronously to spare the datapath
> from blocking on RTE Flow API and allow it to continue with packet processing.
> Enqueue flow rules operations and poll for the results later.
>
> testpmd examples are part of the patch series. PMD changes will follow.
