Subject: net/mlx5e: TLS, Read capabilities only when it is safe
Patch-mainline: v4.19-rc6
Git-commit: 8f92e35aff9692028279d3c03e88547df6d15020
References: bsc#1103990 FATE#326006
Read TLS caps from the core driver only when TLS is supported, i.e
mlx5_accel_is_tls_device returns true.
Fixes: 790af90c00d2 ("net/mlx5e: TLS, build TLS netdev from capabilities")
