Subject: [PATCH 03/19] net/hns3: fix the lock protection of RSS flow rule
Date: Fri, 30 Sep 2022 15:22:04 +0800	[thread overview]
Message-ID: <20220930072220.20753-4-liudongdong3@huawei.com> (raw)
In-Reply-To: <20220930072220.20753-1-liudongdong3@huawei.com>

From: Huisong Li <lihuisong@huawei.com>

RSS flow rules are saved in RSS filter linked list. The linked
list is modified by rte_flow API and is used to restore RSS rules
during reset process. So this patch uses 'hw->flows_lock' to protect
the configuration and recovery of RSS rule.

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