Subject: [PATCH net-next 5/8] net: hns3: make struct hns3_enet_ring cacheline aligned
Date: Sat, 19 Oct 2019 16:03:53 +0800 [thread overview]
Message-ID: <1571472236-17401-6-git-send-email-tanhuazhong@huawei.com> (raw)
In-Reply-To: <1571472236-17401-1-git-send-email-tanhuazhong@huawei.com>
From: Yunsheng Lin <linyunsheng@huawei.com>
Since struct hns3_enet_ring is a frequently used in critical data
path, so make it cacheline aligned as struct hns3_enet_tqp_vector.
