bound to netuio\nwith the help of \"netuio\" class device changes.\nNow Windows will support both \"netuio\" and \"net\" device class and\ncan set kernel driver type based on the device class selection.\n\nNote: Few definitions and structures have been copied from\nnetuio_interface.h file from\n(\"[v5] windows/netuio: add Windows NetUIO kernel driver\") series\nand this will be fixed once the exact path for netuio source code is known.\n\nv7 changes:\n\tRemoved device property key from pci_netuio.c as Numa detection\n\tis done only in pci.c file\nv6 changes:\n\t- Split up the get_netuio_device_info() function into smaller\n\t functions\n\t- Moved get numa node id code to get_device_resource_info() in\n\t order to work on both RTE_PCI_KDRV_NONE and RTE_PCI_KDRV_NIC_UIO\nv5 changes:\n\tChanged when netuio driver handle is closed\nv4 changes:\n\tRemoved 'reserved' member as it is not used\nv3 changes:\n\tRemoved the casts\nv2 changes:\n\t- Moved all netuio specific definitions and functions to\n\t pci_netuio.c and pci_netuio.h files\n\t- Added a single function call to scan all the devices\n\nSigned-off-by: John Alexander
