(vhost: support selective datapath);
ifc VF is compatible with virtio vring operations, this driver implements
vDPA driver ops which configures ifc VF to be a vhost data path accelerator.
ifcvf driver uses vdev as a control domain to manage ifc VFs that belong
to it. It registers vDPA device ops to vhost lib to enable these VFs to be
used as vhost data path accelerator.
Live migration feature is supported by ifc VF and this driver enables
it based on vhost lib.
vDPA needs to create different containers for different devices, thus this
patch set adds APIs in eal/vfio to support multiple container.
Thanks for this! That will avoind having to duplicate these functions
for every new offload driver.

Still, I'm not convinced the offload device should be a virtual device.
It is a real PCI device, why not having a new device type for offload
devices, and let the device to be probed automatically by the existing
device model?
Thanks,
Maxime
