Subject: [PATCH 067/189] net/hns3: fix reporting undefined speed
|
|
|
|
There may be a case in future that the speed obtained from firmware
|
|
is undefined (such as, 400G or other rate), and link status of device is
|
|
up. At this case, PMD driver will reports 100Mbps to the user in the
|
|
"hns3_dev_link_update" API, which is unreasonable. Besides, if the
|
|
speed from firmware is zero, driver should report zero instead of
|
|
100Mbps.
|
|
