Subject: [net-next 11/14] net/mlx5e: kTLS, Improve TLS RX workqueue scope
Date: Mon, 1 Feb 2021 22:54:54 -0800 [thread overview]
Message-ID: <20210202065457.613312-12-saeed@kernel.org> (raw)
In-Reply-To: <20210202065457.613312-1-saeed@kernel.org>
From: Tariq Toukan <tariqt@nvidia.com>
The TLS RX workqueue is needed only when kTLS RX device offload
is supported.
Move its creation from the general TLS init function to the
kTLS RX init.
Create it once at init time if supported, avoid creation/destroy
everytime the feature bit is toggled.
