Enable user to create vdpasim net simulate devices.
Show vdpa management device that supports creating, deleting vdpa devices.
$ vdpa mgmtdev show
vdpasim_net:
supported_classes
net
$ vdpa mgmtdev show -jp
{
"show": {
"vdpasim_net": {

Enable user to query vdpa device information.
$ vdpa dev add mgmtdev vdpasim_net name foo2
Show the newly created vdpa device by its name:
$ vdpa dev show foo2
foo2: type network mgmtdev vdpasim_net vendor_id 0 max_vqs 2 max_vq_size 256
$ vdpa dev show foo2 -jp

Add the ability to add and delete a vdpa device.
Examples:
Create a vdpa device of type network named "foo2" from
the management device vdpasim:
$ vdpa dev add mgmtdev vdpasim_net name foo2
Delete the vdpa device after its use:
$ vdpa dev del foo2

In a subsequent patch, when user initiated command creates a vdpa device,
the user chooses the name of the vdpa device.
To support it, extend the device allocation API to consider this name
specified by the caller driver.

To add one or more VDPA devices, define a management device which
allows adding or removing vdpa device. A management device defines
set of callbacks to manage vdpa devices.
To begin with, it defines add and remove callbacks through which a user

This patchset covers user requirements for managing existing vdpa devices,
