[dpdk-stable] [PATCH 1/6] net/hns3: fix RSS hardware configuration restore failure

[Wei Hu (Xavier)]

From: Hao Chen <chenhao164 at 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")
