mlx5e compilation failure

On mlx5e fails to compile on the latesst net-next:

  CC      drivers/net/ethernet/mellanox/mlx5/core/en_main.o
In file included from ../drivers/net/ethernet/mellanox/mlx5/core/en_tc.h:40,
                 from ../drivers/net/ethernet/mellanox/mlx5/core/en_main.c:45:

   24 |  enum mlx5_flow_match_level match_level;
      |                             ^~~~~~~~~~~

With this .config snippet:
    CONFIG_MLX5_CORE=y
    # CONFIG_MLX5_FPGA is not set
    CONFIG_MLX5_CORE_EN=y
    # CONFIG_MLX5_EN_ARFS is not set
    CONFIG_MLX5_EN_RXNFC=y
    CONFIG_MLX5_MPFS=y
    # CONFIG_MLX5_ESWITCH is not set
    CONFIG_MLX5_CORE_EN_DCB=y
    # CONFIG_MLX5_CORE_IPOIB is not set
    # CONFIG_MLX5_SF is not set

Presumably because ESWITCH is not enabled.

Thanks Jonathan for the report,

this patch should fix the issue:
