Subject: [dpdk-dev] [PATCH 5/5] net/hns3: fix key length when configuring RSS
Date: Fri, 22 May 2020 17:21:18 +0800
Message-ID: <1590139278-11046-6-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>

When users set the length of rss hash key greater than the supported
length by hardware, the pmd driver should intercept and can not
configure the wrong key into the hardware.

Fixes: c37ca66f2b27 ("net/hns3: support RSS")
Cc: stable@dpdk.org
