RH-Commit: [17/25] de71f2e8fc7b25f5197101703fbb5ff054ada984 (redhat/centos-stream/src/qemu-kvm)
|
|
|
|
It allows per-net client operations right after device's successful
|
|
start. In particular, to load the device status.
|
|
|
|
Vhost-vdpa net will use it to add the CVQ buffers to restore the device
|
|
status.
