> This patch adds implementations to probe PCI devices bound to netuio with
> the help of "netuio" class device changes.
> Now Windows will support both "netuio" and "net" device class and can set
> kernel driver type based on the device class selection.
> 
> Note: Few definitions and structures have been copied from
> netuio_interface.h file from ("[v5] windows/netuio: add Windows NetUIO
> kernel driver") series and this will be fixed once the exact path for netuio
> source code is known.
> 
> v6 changes:
>         - Split up the get_netuio_device_info() function into smaller
>           functions
>         - Moved get numa node id code to get_device_resource_info() in
>           order to work on both RTE_PCI_KDRV_NONE and
> RTE_PCI_KDRV_NIC_UIO
> v5 changes:
>         Changed when netuio driver handle is closed
> v4 changes:
>         Removed 'reserved' member as it is not used
> v3 changes:
>         Removed the casts
> v2 changes:
>         - Moved all netuio specific definitions and functions to
>           pci_netuio.c and pci_netuio.h files
>         - Added a single function call to scan all the devices

The whole ifdef section and the devpkey.h include can be removed since Numa detection is done in pci.c.
