Subject: [PATCH] net/hns3: increase time waiting for PF reset completion
|
|
|
|
On the case that PF and VF need to be reset, after the hardware reset is
|
|
complete, VF needs wait for 1 second to restore the configuration so
|
|
that VF does not fail to recover because PF reset isn't complete. But
|
|
the estimated time is not sufficient. This patch fixes it to 5 seconds.
