Subject: [dpdk-dev] [PATCH 2/6] net/hns3: modify write reg opt API impl
Date: Mon, 26 Apr 2021 11:34:48 +0800	[thread overview]
Message-ID: <1619408092-54050-3-git-send-email-humin29@huawei.com> (raw)
In-Reply-To: <1619408092-54050-1-git-send-email-humin29@huawei.com>

From: Chengwen Feng <fengchengwen@huawei.com>

This patch modifies hns3_write_reg_opt() API implementation because
the rte_write32() already uses rte_io_wmb().
