Let's don't do the check here. It's the responsibility of driver to
decide what it should do.

[PATCH V4 0/5] vDPA support
Hi all:
This is an update version of vDPA support in kernel.
vDPA device is a device that uses a datapath which complies with the
virtio specifications with vendor specific control path. vDPA devices
can be both physically located on the hardware or emulated by
software. vDPA hardware devices are usually implemented through PCIE
with the following types:
- PF (Physical Function) - A single

[PATCH V2 0/5] vDPA support
Hi all:
This is an updated version of kernel support for vDPA device. Various
changes were made based on the feedback since last verion. One major
change is to drop the sysfs API and leave the management interface for
future development, and introudce the incremental DMA bus
operations. Please see changelog for more information.
The work on vhost, IFCVF (intel VF driver for vDPA) and qemu is
