[net 07/12] net/mlx5e: Disable hw-tc-offload when MLX5_CLS_ACT config is disabled

From: Saeed Mahameed <saeedm@nvidia.com>
Date: 2021-01-27 04:32:49
Subsystem: mellanox ethernet driver (mlx5e), mellanox mlx5 core vpi driver, networking drivers, the rest · Maintainers: Saeed Mahameed, Tariq Toukan, Mark Bloch, Leon Romanovsky, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Linus Torvalds

From: Maor Dickman <redacted>

The cited commit introduce new CONFIG_MLX5_CLS_ACT kconfig variable
to control compilation of TC hardware offloads implementation.
When this configuration is disabled the driver is still wrongly
reports in ethtool that hw-tc-offload is supported.

Fixed by reporting hw-tc-offload is supported only when
CONFIG_MLX5_CLS_ACT is enabled.

Fixes: d956873f908c ("net/mlx5e: Introduce kconfig var for TC support")
