Subject: [mlx5-next 16/17] net/mlx5: Add reset_state field to MFRL register
Date: Tue, 22 Feb 2022 21:09:31 -0800	[thread overview]
Message-ID: <20220223050932.244668-17-saeed@kernel.org> (raw)
In-Reply-To: <20220223050932.244668-1-saeed@kernel.org>

From: Moshe Shemesh <moshe@nvidia.com>

state of sync reset for fw update. This field enables sharing with the
