Subject: Flexible payload feature of i40e PMD in DPDK 20.11
Date: Tue, 31 Jan 2023 18:44:51 +0000	[thread overview]
Message-ID: <MN0PR84MB3047C7F7EF940AAD3775E3D6ECD09@MN0PR84MB3047.NAMPRD84.PROD.OUTLOOK.COM> (raw)

Hi,

I have the following configuration:

NIC: Intel XXV710 (supported by i40e PMD)
DPDK version: 20.11

My requirement is to use Flexible payload of the XXV710 NIC (i40e PMD) to do the following:

* For incoming packets where the ethertype is 0x0806 (ie: ARP packets), do the RSS hashing based on the Sender Hardware Address instead of the ethertype field which is considered by default. 
* Basically, I don't want all the ARP packets falling on the same queue. Hence, hashing based on the sender hardware address would give a good distribution across multiple CPUs where my dpdk application is running.


However, I have not been able to find any examples where the following macros have been used - RTE_ETH_INPUT_SET_FLEX_PAYLOAD_1ST_WORD through RTE_ETH_INPUT_SET_FLEX_PAYLOAD_8TH_WORD.


Any pointers would be much appreciated.

Regards,
Venkatesh
