Subject: [PATCH 133/189] net/hns3: fix processing link status message on PF
|
|
|
|
The opcode of the link status notification message reported by the
|
|
firmware is zero, it will be filtered out because driver treats it as
|
|
already processed message. As a result, the PF can't update the link
|
|
status in a timely manner.
|
|
|
|
Because only VF can set opcode to zero when processing mailbox message,
|
|
we add a judgment to make sure the PF messages will not be filtered out.
|
|
|
|
Fixes: dbbbad23e380 ("net/hns3: fix VF handling LSC event in secondary process")
