Subject: [PATCH mlx5-next 0/5] Drop Mellanox FPGA TLS support from the kernel

From: Leon Romanovsky <leonro@...dia.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,
clean build config options and delete useless kTLS vs. TLS separation.

Thanks

BTW, the target of this series is mlx5-next, as other series removes
FPGA IPsec together with relevant cleanup in RDMA side.

Leon Romanovsky (5):
  net/mlx5_fpga: Drop INNOVA TLS support
  net/mlx5: Reliably return TLS device capabilities
  net/mlx5: Remove indirection in TLS build
  net/mlx5: Remove tls vs. ktls separation as it is the same
  net/mlx5: Cleanup kTLS function names and their exposure
