How to enable RSS for QinQ for Intel XL710?

[yduan6]

Hello,

Do you know how to enable RSS for QinQ traffic for Intel XL710?

The RSS hash is always 0, but I need put traffic into diff queues by 5-tuple or 4-tuple.

My conf is below:

   struct rte_eth_conf port_conf = {

           .rxmode = {

               .mq_mode   = ETH_MQ_RX_RSS,

               .split_hdr_size = 0,

               .offloads = DEV_RX_OFFLOAD_CHECKSUM,

           },

           .rx_adv_conf = {

               .rss_conf = {

                   .rss_key = NULL,

                   .rss_hf = ETH_RSS_IP,

               },

           },

           .txmode = {

               .mq_mode = ETH_MQ_TX_NONE,

           }

   };

Thanks

BTW, I 'd already asked the same question at Intel Premier Support(Case Number 00486656), and they have no idea about this question.
