Looks like this needs to check and just skip the write if
ready == 0, right? Of course vdpa core then insists on calling
vp_vdpa_get_vq_ready which will warn. Maybe...

[PATCH 0/5] vDPA/ifcvf: implement immediate initialization mechanism
Formerly, ifcvf driver has implemented a lazy-initialization mechanism

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
