Subject: [dpdk-dev] [PATCH v7 5/9] common/mlx5: create GENEVE TLV option object with DevX
Date: Sun, 17 Jan 2021 12:21:19 +0200
Message-ID: <20210117102123.19045-6-shirik@nvidia.com> (raw)
In-Reply-To: <20210117102123.19045-1-shirik@nvidia.com>

TLV object is a special firmware maintained entity used
to support match on GENEVE header extension option.

The TLV object is created with DevX API and accepts
the option class, type and lehgth fields.

The class type and length fields are set using MLX5_SET
and the Devx object is created using mlx5 glue function.
