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

Subject: RSS on L2TP, Teredo, PPPoE Tunnels

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:
    1. This is not supported by adapter.                             
  1. testpmd> flow tunnel create  0 type “”:
    1.  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
