Subject: [PATCH net 2/3] net/mlx5: HWS, ignore flow level for multi-dest table

From: Yevgeny Kliteynik <kliteyn@...dia.com>

When HWS creates multi-dest FW table and adds rules to
forward to other tables, ignore the flow level enforcement
in FW, because HWS is responsible for table levels.

This fixes the following error:

  mlx5_core 0000:08:00.0: mlx5_cmd_out_err:818:(pid 192306):
     SET_FLOW_TABLE_ENTRY(0x936) op_mod(0x0) failed,
     status bad parameter(0x3), syndrome (0x6ae84c), err(-22)

Fixes: 504e536d9010 ("net/mlx5: HWS, added actions handling")
