Subject: [dpdk-dev] [PATCH v2 1/8] lib/librte_ethdev: introduce GENEVE header TLV option item
Date: Tue, 5 Jan 2021 19:53:50 +0200 [thread overview]
Message-ID: <20210105175358.16712-2-shirik@nvidia.com> (raw)
In-Reply-To: <20210105175358.16712-1-shirik@nvidia.com>
The Geneve tunneling protocol is designed to allow the
user to specify some data context on the packet.
The GENEVE TLV (Type-Length-Variable) Option
is the mean intended to present the user data.
In order to support GENEVE TLV Option the new rte_flow
item "rte_flow_item_geneve_opt" is added.
The new item contains the values and masks for the
following fields:
-option class
-option type
-length
-data
New item will be added to testpmd to support match and
raw encap/decap actions.
