Subject: [PATCH net-next RFC v3 08/14] net/mlx5: Handle sync reset abort event
Date: Sun, 30 Aug 2020 18:27:28 +0300 [thread overview]
Message-ID: <1598801254-27764-9-git-send-email-moshe@mellanox.com> (raw)
In-Reply-To: <1598801254-27764-1-git-send-email-moshe@mellanox.com>
If firmware sends sync_reset_abort to driver the driver should clear the
reset requested mode as reset is not expected any more.
