[PATCH 0/5] vDPA/ifcvf: implement immediate initialization mechanism
Formerly, ifcvf driver has implemented a lazy-initialization mechanism
for the virtqueues and other config space contents,
it would store all configurations that passed down from the userspace,
then load them to the device config space upon DRIVER_OK.
This can not serve live migration, so this series implement an
immediate initialization mechanism, which means rather than the
former store-load
