[PATCH 3/5] retire ifcvf_start_datapath and ifcvf_add_status
Rather than former lazy-initialization mechanism, now the virtqueue operations and driver_features related ops access the virtio registers directly to take immediate actions. So ifcvf_start_datapath() should retire. ifcvf_add_status() is retierd because we should not change device status by a vendor driver's decision, this driver should only set device status which is from virito drivers upon

[PATCH V2 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

[PATCH V2 2/5] vDPA/ifcvf: get_driver_features from virtio registers
This commit implements a new function ifcvf_get_driver_feature() which read driver_features from virtio registers. To be less ambiguous, ifcvf_set_features() is renamed to ifcvf_set_driver_features(), and ifcvf_get_features() is renamed to ifcvf_get_dev_features() which returns the provisioned vDPA device features.
