Subject: [PATCH 04/19] net/hns3: fix RSS flow rule restore failed
Date: Fri, 30 Sep 2022 15:22:05 +0800	[thread overview]
Message-ID: <20220930072220.20753-5-liudongdong3@huawei.com> (raw)
In-Reply-To: <20220930072220.20753-1-liudongdong3@huawei.com>

From: Huisong Li <lihuisong@huawei.com>

After reset process, types of RSS flow rule cannot be restored when
load driver without RTE_ETH_MQ_RX_RSS_FLAG flag. This is because the
restoration for RSS flow rule is done in the 'hns3_config_rss()'. But
this function is also used to configure and restore RSS configuration
from ethdev ops, and doesn't configure RSS types if 'rxmode.mq_mode'
has not the flag. As a result, RSS types configured by rte flow API
can't be restored in this case when encounter reset. Actually, all
RSS rules are saved to a global link list. This patch uses the linked
list to restore RSS flow rule.

Fixes: 920be799dbc3 ("net/hns3: fix RSS indirection table configuration")
