[libvirt PATCH v2 0/3] Add support for vDPA network devices

[Jonathon Jongsma]

vDPA network devices allow high-performance networking in a virtual
machine by providing a wire-speed data path. These devices require a
vendor-specific host driver but the data path follows the virtio
specification.

The support for vDPA devices was recently added to qemu. This allows
libvirt to support these devices. It requires that the device is
configured on the host with the appropriate vendor-specific driver.
This will create a chardev on the host at e.g. /dev/vhost-vdpa-0. That
chardev path can then be used to define a new interface with
type='vdpa'.

Changes in v2:
 - split patches
 - add qemu capability
 - disallow migration for vdpa devices
