Subject: [PATCH mlx5-next 1/6] net/mlx5: Add new timestamp mode bits
Date: Fri, 12 Feb 2021 14:30:37 -0800 [thread overview]
Message-ID: <20210212223042.449816-2-saeed@kernel.org> (raw)
In-Reply-To: <20210212223042.449816-1-saeed@kernel.org>
From: Aharon Landau <aharonl@nvidia.com>
These fields declare which timestamp mode is supported by the device
per RQ/SQ/QP.
In addition add the ts_format field to the select the mode for
RQ/SQ/QP.
