RH-Commit: [19/21] 439b4133a757b2f1c5f4a1441eca25329896491a (eperezmartin/qemu-kvm)
|
|
Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=2114060
|
|
Upstream status: git@github.com:jasowang/qemu.git net-next
|
|
|
|
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.
