From d2fe85e2b088b99decbd4d394071fffbb6d80ff2 Mon Sep 17 00:00:00 2001 From: Huisong Li Date: Sun, 25 Apr 2021 20:06:28 +0800 Subject: [PATCH 138/189] net/hns3: fix link status when port is stopped When port is stopped, link down should be reported to user. For HNS3 PF driver, link status comes from link status of hardware. If the port supports NCSI feature, hardware MAC will not be disabled. At this case, even if the port is stopped, the link status is still Up. So driver should set link down when the port is stopped.
