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.
|
|
|
|
