Subject: [PATCH net-next 11/12] net: hns3: remove RXD_VLD check in hns3_handle_bdinfo
Date: Fri, 28 Jun 2019 19:50:17 +0800 [thread overview]
Message-ID: <1561722618-12168-12-git-send-email-tanhuazhong@huawei.com> (raw)
In-Reply-To: <1561722618-12168-1-git-send-email-tanhuazhong@huawei.com>
From: Yunsheng Lin <linyunsheng@huawei.com>
The HNS3_RXD_VLD_B bit has already been checked in hns3_add_frag
or hns3_handle_rx_bd before calling hns3_handle_bdinfo, so when
hns3_handle_bdinfo is called, the HNS3_RXD_VLD_B bit is always
set, which makes the checking in hns3_handle_bdinfo unnecessary.
This patch removes the RXD_VLD_B checking in hns3_handle_bdinfo.
