Hello,
The Flex item API allows to extend network protocols provided in port hardware.
The API allows DPDK application build a custom network protocol parser after providing the protocol description.
You can create a Flex item for network protocols you’ve mentioned over mlx5 BlueField-2 ports.
Regards,
Gregory

Hello DPDK Team,
Hope you guys are doing great !!
We are developing application with dpdk 22.03 & Mellanox Connectx-6 adapter,
Want to use IP-Port tuples (Inner in case of tunnels) to RSS traffic to multiple queues.
We need to handle L2TPv2/3, Teredo, PPPoE etc, but adapter have limited tunnels support.
Is there a way/possibility in DPDK to support mentioned or define user specific tunnels & achieve RSS on inner tuples ?
From documentation, we came across these approaches:
1. Rte flow Flex item:
* This is not supported by adapter.
1. testpmd> flow tunnel create 0 type “”:
* Not getting documentation to check.
Please suggest.
Environment:
* OS: Ubuntu 20.04
* Driver: MLNX_OFED_LINUX-5.5-1.0.3.2
* Firmware: 22.32.2004
Regards,
Tarun Badnora
