Subject[PATCH 5.4 286/309] net/mlx5: Deprecate usage of generic TLS HW capability bit
Date
From: Tariq Toukan <tariqt@mellanox.com>

[ Upstream commit 61c00cca41aeeaa8e5263c2f81f28534bc1efafb ]

Deprecate the generic TLS cap bit, use the new TX-specific
TLS cap bit instead.

Fixes: a12ff35e0fb7 ("net/mlx5: Introduce TLS TX offload hardware bits and structures")
