Subject: [PATCH 177/283] net: hns3: handle empty unknown interrupt for VF
|
|
|
|
mainline inclusion
|
|
from mainline-v5.17-rc2
|
|
commit 2f61353cd2f789a4229b6f5c1c24a40a613357bb
|
|
category: bugfix
|
|
bugzilla: https://gitee.com/src-openeuler/kernel/issues/I8EN3D
|
|
CVE: NA
|
|
|
|
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=2f61353cd2f789a4229b6f5c1c24a40a613357bb

----------------------------------------------------------------------
|
|
|
|
Since some interrupt states may be cleared by hardware, the driver
|
|
may receive an empty interrupt. Currently, the VF driver directly
|
|
disables the vector0 interrupt in this case. As a result, the VF
|
|
is unavailable. Therefore, the vector0 interrupt should be enabled
|
|
in this case.
|
|
