Subject: [PATCH mlx5-next 1/5] net/mlx5_fpga: Drop INNOVA TLS support
Date:   Mon,  4 Apr 2022 15:08:15 +0300

From: Leon Romanovsky <leonro@nvidia.com>

Mellanox INNOVA TLS cards are EOL in May, 2018 [1]. As such, the code
is unmaintained, untested and not in-use by any upstream/distro oriented
customers. In order to reduce code complexity, drop the kernel code.
