Subject: [PATCH net-next v2 4/6] net/x25: support NETDEV_CHANGE notifier
Date: Mon, 16 Nov 2020 14:55:24 +0100 [thread overview]
Message-ID: <20201116135522.21791-5-ms@dev.tdt.de> (raw)
In-Reply-To: <20201116135522.21791-1-ms@dev.tdt.de>
This makes it possible to handle carrier lost and detection.
In case of carrier lost, we shutdown layer 3 and flush all sessions.
Signed-off-by: Martin Schiller <ms@dev.tdt.de>
