Subject: [dpdk-dev] [PATCH 4/5] net/hns3: add RSS hash offload to port Rx configuration
Date: Fri, 22 May 2020 17:21:17 +0800
Message-ID: <1590139278-11046-5-git-send-email-xavier.huwei@huawei.com> (raw)
In-Reply-To: <1590139278-11046-1-git-send-email-xavier.huwei@huawei.com>

From: Lijun Ou <oulijun@huawei.com>

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`.

Fixes: 19a3ca4c99cf ("net/hns3: add start/stop and configure operations")
Fixes: c37ca66f2b27 ("net/hns3: support RSS")
