Subject: [PATCH net-next 11/11] net: hns3: use lower_32_bits and upper_32_bits
Date: Thu, 28 Jun 2018 12:12:29 +0800 [thread overview]
Message-ID: <1530159149-122284-12-git-send-email-lipeng321@huawei.com> (raw)
In-Reply-To: <1530159149-122284-1-git-send-email-lipeng321@huawei.com>
From: Huazhong Tan <tanhuazhong@huawei.com>
MACRO lower_32_bits and upper_32_bits can help to get bits 0-31
and bits 32-63 of a number, so just use it.
