Subject: [net-next V2 13/15] net/mlx5e: Block TLS device offload on combined SD netdev
From: Tariq Toukan <tariqt@...dia.com>
1) Each TX TLS device offloaded context has its own TIS object. Extra work
is needed to get it working in a SD environment, where a stream can move
between different SQs (belonging to different mdevs).
2) Each RX TLS device offloaded context needs a DEK object from the DEK
pool.
Extra work is needed to get it working in a SD environment, as the DEK
pool currently falsely depends on TX cap, and is on the primary device
only.
Disallow this combination for now.
