Subject: net/mlx5e: Remove non-essential TLS SQ state bit
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2f014f4016db44103864d295ba427eb1e0086551;p=linux.git

net/mlx5e: Remove non-essential TLS SQ state bit

Maintaining an SQ state bit to indicate TLS support
has no real need, a simple and fast test [1] for the SKB is
almost equally good.

[1] !skb->sk || !tls_is_sk_tx_device_offloaded(skb->sk)
