Subsequent patch needs to
(a) query and use socket family
(b) send/receive messages using this family
Hence add helper routines to open, close, query family and to perform
send receive operations.

Linux vdpa interface allows vdpa device management functionality.
This includes adding, removing, querying vdpa devices.
vdpa interface also includes showing supported management devices
which support such operations.
This patchset includes kernel uapi headers and a vdpa tool.
examples:
$ vdpa
In subsequent patch need to map a string to a unsigned int.
Hence, add an API to map a string to unsigned int.

This backend acts as the counterpart to the Vdmabuf Virtio frontend.
When it receives a new export event from the frontend, it raises an
event to alert the Qemu UI/userspace. Qemu then "imports" this buffer
using the Unique ID.
As part of the import step, a new dmabuf is created on the Host using
After registering with this notifier, other drivers that are dependent
on KVM can get notified whenever a VM is created or destroyed. This
also provides a way for sharing the KVM instance pointer with other
drivers.

The Virtual Dmabuf or Virtio based Dmabuf (Vdmabuf) driver can be used
to "transfer" a page-backed dmabuf created in the Guest to the Host
without making any copies. This is mostly accomplished by recreating the
dmabuf on the Host using the PFNs and other meta-data shared by the guest.
