[PATCH mlx5-next 3/5] net/mlx5: Remove indirection in TLS build
From: Leon Romanovsky
Date: Mon Apr 04 2022 - 08:08:47 EST
From: Leon Romanovsky <leonro@xxxxxxxxxx>
The dream described in the commit 1ae173228489 ("net/mlx5: Accel, Add TLS
tx offload interface") never came true, even an opposite happened when FPGA
TLS support was dropped. Such removal revealed the problematic flow in the
build process: build of unrelated files in case of TLS or IPsec are enabled.
In both cases, the MLX5_ACCEL is enabled, which built both TLS and IPsec.
As a solution, simply merge MLX5_TLS and MLX5_EN_TLS options and move TLS
related files to the eth part of the mlx5_core.
