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 ser
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 vDP
In this commit, virtqueue operations including:
set_vq_num(), set_vq_address(), set_vq_ready()
and get_vq_ready() access PCI registers directly
to take immediate actions.

VIRTIO_CONFIG_S_FAILED indicates the guest driver has given up
the device due to fatal errors. So it is the guest decision,
the vendor driver should not set this status to the device.

This commit synchronize irqs of the virtqueues
and config space in the reset routine.
Thus ifcvf_stop_hw() and reset() are refactored as well.

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 vend

When initializing XDP in virtnet_open(), some rq xdp initialization
may hit an error causing net device open failed. However, previous
rqs have already initialized XDP and enabled NAPI, which is not the
expected behavior. Need to roll back the previous rq initialization
to avoid leaks in error unwi
