From: Chiqijun <chiqijun@huawei.com> driver inclusion category: bugfix bugzilla: 4472 ----------------------------------------------------------------------- During the loopback test, it cannot be guaranteed that the protocol stack will completely stop sending packets, which causes the loopback test packets and protocol stack packets to be sent at the same time, causing the loopback test to fail. This patch corrects it.
