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:

a. This is not supported by adapter.                             

2. testpmd> flow tunnel create  0 type “”:

a.  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
