Miniport Driver with a WDM Lower Interface (NDIS 5.1)

Note   NDIS 5. x has been deprecated and is superseded by NDIS 6. x. For new NDIS driver development, see Network Drivers Starting with Windows Vista. For information about porting NDIS 5. x drivers to NDIS 6. x, see Porting NDIS 5.x Drivers to NDIS 6.0.

A miniport driver with a Windows Driver Model(WDM) lower interface is also known as an NDIS-WDM miniport driver. Such a miniport driver:
  • Uses a WDM lower edge.

  • Can call both NDIS and non-NDIS functions. However, whenever possible, the miniport driver should call NDIS functions.

  • Can initialize a miniport instance that is used to control devices attached to a particular bus and that communicates with those devices over that bus.

For example, a miniport driver that controls devices on either Universal Serial Bus (USB) or IEEE 1394 (firewire) buses must expose a standard NDIS miniport driver interface at its upper edge and use the class interface for the particular bus at its lower edge. Such a miniport driver communicates with devices that are attached to the bus by sending I/O request packets (IRPs) to the bus.
