Subject: [PATCH 096/189] net/hns3: fix configure FEC when concurrent with
|
|
reset
|
|
|
|
Currently, after the reset is complete, the PMD restores the FEC
|
|
according to the FEC configuration reserved in the driver. If there is a
|
|
concurrency between the FEC setup operation and the restore operation
|
|
after a reset, the FEC status of the last hardware may be unknown.
|
|
|
|
This patch adds the step of obtaining the lock when setting the FEC to
|
|
avoid concurrency between restore operation and setting operation.
|
|
|
