Important

This topic is part of the WDI driver model released in Windows 10. The WDI driver model is in maintenance mode and will only receive high priority fixes. WiFiCx is the Wi-Fi driver model released in Windows 11. We recommend that you use WiFiCx to take advantage of the latest features.

The NDIS_MINIPORT_DRIVER_WDI_CHARACTERISTICS structure defines the set of handlers that a WDI miniport driver must implement. It is used by the IHV driver to register additional handlers for the control path and the full set of handlers for the data path.
