Subject: [dpdk-users] RSS logic for Intel XXV710 NIC cards (i40e driver)
Date: Thu, 4 Feb 2021 15:35:01 +0000
Message-ID: <AT5PR8401MB1027FD9745D1818A64177951ECB39@AT5PR8401MB1027.NAMPRD84.PROD.OUTLOOK.COM> (raw)


I'm running into some issues in activating the RSS logic for Intel XXV710 NIC cards.

Here are the details:

* DPDK Version: 20.08
* XXV710 NIC cards:
  - driver: i40e
  - version: 2.11.29
  - firmware-version: 8.15 0x80009586 1.1691.0

I got some pointers from the following links:

However, the functions used in the prototype code here:
- rte_eth_dev_filter_supported()
- rte_eth_dev_filter_ctrl()

are marked deprecated in DPDK 20.08 and are not present in DPDK 20.11.

I'm currently using DPDK 20.08 but there is a plan to move to DPDK 20.11 since it is an LTS release.

I also went through the following link:

But, I couldn't figure out the APIs that I need to program the RSS hashing logic correctly.

My code: Currently, I have the following snippet of code:
static struct rte_eth_conf port_conf = {
    .rxmode = {
        .max_rx_pkt_len = 1600,
        .split_hdr_size = 0,
        .mq_mode        = ETH_MQ_RX_RSS, 
    .rx_adv_conf = {
        .rss_conf = {
            .rss_key     = NULL,
            .rss_hf      = ETH_RSS_IP |
                           ETH_RSS_UDP |
    .txmode = {
        .mq_mode = ETH_DCB_NONE,
        .offloads = DEV_TX_OFFLOAD_MULTI_SEGS,

I also read some helpful posts that mentioned that the rte_flow APIs can be used to program RSS logic for i40e driver. But, I haven't been able to find the exact details.

Any pointers on how to program the RSS logic on the XXV710 NICs would be most helpful.
