Subject: [dpdk-dev] [PATCH 1/6] net/hns3: fix RSS hardware configuration restore failure
Date: Fri, 22 Nov 2019 20:39:49 +0800
Message-ID: <20191122123954.17911-2-xavier.huwei@tom.com> (raw)
In-Reply-To: <20191122123954.17911-1-xavier.huwei@tom.com>

From: Hao Chen <chenhao164@huawei.com>

This patch fixes the bug that hardware configuration called
tc_size doesn't restore to the initial value when starting
the app, configuring PFC and then restarting the app,
because of the tc_mode didn't initial when rss is disabled.

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