[PATCH 0/9] net/mlx5: flow fast path validation

[Dariusz Sosnowski]

This patchset adds validations for flow items and actions
supplied by the user to fast path async flow API functions
implemented in mlx5 PMD.

- Patch 1: Adds the ability to generically calculate
  flow item's mask size using rte_flow_conv().
  This change is used in follow up patches to check for
  non-zero mask in pattern template.
- Patches 2-7: Prepares mlx5 PMD for adding fast path validations.
  Specifically:

  - Required functionality for validating queue indexes and
    target represented ports are extracted for reuse.
  - Additional info, required for validation, is stored in
    pattern and actions templates.
  - Introduces mlx5_fp_debug_enabled() function for checking
    if mlx5 PMD was compiled in debug mode.

- Patch 8: Introduce validations to:

  - rte_flow_async_create()
  - rte_flow_async_create_by_index()
  - rte_flow_async_actions_update()
  - rte_flow_async_destroy()

  These validations are enabled if and only if
  RTE_LIBRTE_MLX5_DEBUG macro is defined during compilation.
