net/mlx5: fix 32-bit arch compilation issue
Checks
Commit Message
There is a "cast to pointer from integer of different size"
compilation failure on 32-bit machines introduced by the
RTE_FLOW_ACTION_TYPE_MODIFY_FIELD implementation in mlx5 PMD.
Cast the specified value to be used as RTE_FLOW_FIELD_POINTER
to a pointer with an appropriate size suited for underlying arch.
Please squash this patch into the original commit if possible.
Fixes: 80ec1e84a4 ("net/mlx5: support modify field flow action")
