Subject: [v6 04/18] net/mlx5: add port to metadata conversion
Date: Thu, 20 Oct 2022 18:57:34 +0300 [thread overview]
Message-ID: <20221020155749.16643-5-valex@nvidia.com> (raw)
In-Reply-To: <20221020155749.16643-1-valex@nvidia.com>
From: Dariusz Sosnowski <dsosnowski@nvidia.com>
This patch initial version of functions used to:
- convert between ethdev port_id and internal tag/mask value,
- convert between IB context and internal tag/mask value.
Signed-off-by: Dariusz Sosnowski <dsosnowski@nvidia.com>
