Subject: [dpdk-dev] [RFC v2] ethdev: introduce GENEVE header extension item
Date: Thu,  3 Sep 2020 10:39:28 +0300
Message-ID: <1599118768-13265-1-git-send-email-shirik@nvidia.com> (raw)

The Geneve tunneling protocol is designed to allow
the user to specify some data context on the packet.
The header extension options is the mean intended
to present the user data. These ones are implemented
in TLV (Type-Length-Value) fashion, in order to
support these Geneve protocol feature we will
introduce the new item “rte_flow_item_geneve_option”

The support for new item will be added to testpmd
and include values and masks for the fields:
- class
- type
- data length
- data itself

The usage example:

"flow create 0 ingress pattern ipv4 / udp /
geneve / geneve_opt class is 102 type is 80
type mask ff data is 10002 data mask is
7fffffff / end actions drop / end "

New item will be added to testpmd to support
raw encap/decap action.
