Subject: [PATCH v2 7/7] net/hns3: remove redundant RSS tuple field
Date: Thu, 5 May 2022 20:27:07 +0800
Message-ID: <20220505122707.61182-8-humin29@huawei.com> (raw)
In-Reply-To: <20220505122707.61182-1-humin29@huawei.com>

From: Huisong Li <lihuisong@huawei.com>

The 'rss_tuple_fields' in struct struct hns3_rss_conf::rss_tuple_sets is
redundant. Because the enabled RSS tuple in PMD is already managed by the
'types' in struct hns3_rss_conf::conf. This patch removes this redundant
variable.

Fixes: c37ca66f2b27 ("net/hns3: support RSS")
