Subject: [dpdk-dev] [PATCH v3 1/2] rte_flow: add eCPRI key fields to flow API
Date: Thu, 2 Jul 2020 20:53:41 +0800 [thread overview]
Message-ID: <1593694422-299952-2-git-send-email-bingz@mellanox.com> (raw)
In-Reply-To: <1593694422-299952-1-git-send-email-bingz@mellanox.com>
Add a new item "rte_flow_item_ecpri" in order to match eCRPI header.
eCPRI is a packet based protocol used in the fronthaul interface of
5G networks. Header format definition could be found in the
specification via the link below:
https://www.gigalight.com/downloads/standards/ecpri-specification.pdf
eCPRI message can be over Ethernet layer (.1Q supported also) or over
UDP layer. Message header formats are the same in these two variants.
