[PATCH v2 19/34] net/mlx5: update ASO resources in non-template setup

[Maayan Kashani]

From: Gregory Etelson <getelson at nvidia.com>

Non-template PMD implementation allocates ASO flow actions resources
on-demand.

Current PMD implementation iterated over actions array in search for
actions that required ASO resources allocations.

The patch replaced the iteration with actions flags bitmap queries.
