Subject: [PATCH net-next RFC 07/13] net/mlx5: Handle sync reset abort event
Date: Mon, 27 Jul 2020 14:02:27 +0300
Message-ID: <1595847753-2234-8-git-send-email-moshe@mellanox.com> (raw)
In-Reply-To: <1595847753-2234-1-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.
