Subject: [PATCH v1 net-next 04/15] net/tls: expose get_netdev_for_sock
Date: Mon, 7 Dec 2020 23:06:38 +0200 [thread overview]
Message-ID: <20201207210649.19194-5-borisp@mellanox.com> (raw)
In-Reply-To: <20201207210649.19194-1-borisp@mellanox.com>
get_netdev_for_sock is a utility that is used to obtain
the net_device structure from a connected socket.
Later patches will use this for nvme-tcp DDP and DDP CRC offloads.
