From fdae939696a09b4010df004be06c491d9294e319 Mon Sep 17 00:00:00 2001 From: Lijun Ou Date: Fri, 22 May 2020 17:21:17 +0800 Subject: [PATCH] net/hns3: add RSS hash offload to Rx configuration Rx offload flag `DEV_RX_OFFLOAD_RSS_HASH` which can be used to enable/disable PMDs write to `rte_mbuf::hash::rss`. The hns3 PMD driver already can notify the validity of `rte_mbuf::hash:rss` to the application by enabling `PKT_RX_RSS_HASH` flag in `rte_mbuf::ol_flags`.
