Subject: [v4 05/18] common/mlx5: query set capability of registers
Date: Wed, 19 Oct 2022 17:42:45 +0300 [thread overview]
Message-ID: <20221019144258.16282-6-valex@nvidia.com> (raw)
In-Reply-To: <20221019144258.16282-1-valex@nvidia.com>
From: Bing Zhao <bingz@nvidia.com>
In the flow table capabilities, new fields are added to query the
capability to set, add, copy to a REG_C_x.
The set capability are queried and saved for the future usage.
