[dpdk-dev] [PATCH v2] net/mlx5: fix limit on direct rules tables number

[Dekel Peled]

MLX5 PMD limits the number of SW steering tables to 32.
This patch updates the limit to 65535, to allow wide range of values.

Fixes: e2b4925ef7c1 ("net/mlx5: support Direct Rules E-Switch")

v2: remove Cc to stable release, not relevant for this fix.
