Goal of this patchset is to improve the throughput of flow insertion and deletion in mlx5 PMD when HW Steering flow engine is used.
- Patch 1 - Use preallocated per-queue, per-actions template buffer for storing translated flow actions, instead of allocating and filling it on demand, on each flow operation. - Patches 2-4 - Make resource index allocation optional. This allocation will be skipped when it is not required by the created template table. - Patches 5-7 - Reduce memory footprint of the internal flow queue. - Patch 8 - Remove indirection between flow job and flow itself, by using flow as an operation container. - Patches 9-10 - Reduce memory footpring of flow struct by moving rarely used flow fields outside of the main flow struct. These fields will accesses only when needed. Also remove unneeded `zmalloc` usage. - Patch 11 - Remove unneeded device status check in flow create. In general all of these changes result in the following improvements (all numbers are averaged Kflows/sec): | | Insertion) | +% | Deletion | +% | |--------------|:----------:|:------:|:--------:|:-----:| | baseline | 6338.7 | | 9739.6 | | | improvements | 6978.8 | +10.1% | 10432.4 | +7.1% | The basic benchmark was run on ConnectX-6 Dx (22.40.1000), on the system with Intel Xeon Platinum 8380 CPU. v2: - Rebased. - Applied Acked-by tags from previous version.
