Subject: [net-next 02/14] net/mlx5: DR, Fix the SMFS sync_steering for fast teardown
Date: Mon, 24 Oct 2022 14:57:22 +0100 [thread overview]
Message-ID: <20221024135734.69673-3-saeed@kernel.org> (raw)
In-Reply-To: <20221024135734.69673-1-saeed@kernel.org>
From: Yevgeny Kliteynik <kliteyn@nvidia.com>
If sync happens when the device is in fast teardown, just bail
and don't do anything, because the PCI device is not there any more.
