Subject: [PATCH 01/16] net/hns3: fix possible truncation of hash key when config
Date: Fri, 10 Mar 2023 17:35:03 +0800 [thread overview]
Message-ID: <20230310093518.5198-2-liudongdong3@huawei.com> (raw)
In-Reply-To: <20230310093518.5198-1-liudongdong3@huawei.com>
From: Huisong Li <lihuisong@huawei.com>
The hash key length of hns3 driver is obtained from firmware. If the
length isn't a multiple of HNS3_RSS_HASH_KEY_NUM (16), the last part
of hash key will be truncated.
Fixes: 4a7384e3c34d ("net/hns3: refactor set RSS hash algorithm and key interface")
Fixes: c37ca66f2b27 ("net/hns3: support RSS")
