Subject: [net 1/9] net/mlx5e: Remove WARN_ON when trying to offload an unsupported TLS cipher/version

From: Saeed Mahameed <[email-masked]>
Date: Thu, 28 Jul 2022 13:46:32 -0700

From: Gal Pressman <[email-masked]>

The driver reports whether TX/RX TLS device offloads are supported, but
not which ciphers/versions, these should be handled by returning
-EOPNOTSUPP when .tls_dev_add() is called.

Remove the WARN_ON kernel trace when the driver gets a request to
offload a cipher/version that is not supported as it is expected.
