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.
