Subject: [dpdk-dev] [PATCH V3 2/6] net/hns3: use unsigned types for bit operator
Date: Mon, 9 Nov 2020 22:28:58 +0800
Message-ID: <1604932142-19900-3-git-send-email-oulijun@huawei.com> (raw)
In-Reply-To: <1604932142-19900-1-git-send-email-oulijun@huawei.com>

From: Hongbo Zheng <zhenghongbo3@huawei.com>

According to bit operator reliability style, variables in
the right expression participating int bit operation
must be an unsigned type.
