Subject: [dpdk-dev] [PATCH v3 3/8] net/mlx5: improve Verbs flow priority discover for scalable
Date: Tue, 19 Oct 2021 18:34:56 +0800	[thread overview]
Message-ID: <20211019103501.2216840-4-xuemingl@nvidia.com> (raw)
In-Reply-To: <20211019103501.2216840-1-xuemingl@nvidia.com>

To detect number flow Verbs flow priorities, PMD try to create Verbs
flows in different priority. While Verbs is not designed to support
ports larger than 255.

When DevX supported by kernel driver, 16 Verbs priorities must be
supported, no need to create Verbs flows.
