如何從NDIS Miniport調用KMDF WDF接口？

我有一個總線驅動程序，爲自定義以太網卡的每個物理端口創建一個PDO。我也有安裝在每個PDO上的NDIS微型端口驅動程序。如何從NDIS Miniport調用KMDF WDF接口？

總線驅動程序基於靜態Toaster示例。 NDIS微型端口基於經過修改以匹配硬件的Netvmini。

ToasterInterface.InterfaceHeader.InterfaceReference = 
    WdfDeviceInterfaceReferenceNoOp; 
ToasterInterface.InterfaceHeader.InterfaceDereference = 
    WdfDeviceInterfaceDereferenceNoOp; 

ToasterInterface.GetCrispinessLevel = Bus_GetCrispinessLevel; 
ToasterInterface.SetCrispinessLevel = Bus_SetCrispinessLevel; 
ToasterInterface.IsSafetyLockEnabled = Bus_IsSafetyLockEnabled; 

WDF_QUERY_INTERFACE_CONFIG_INIT(&qiConfig, 
           (PINTERFACE) &ToasterInterface, 
           &GUID_TOASTER_INTERFACE_STANDARD, 
           NULL);

狀態= WdfDeviceAddQueryInterface（hChild，& qiConfig）;

如何從NDIS驅動程序調用KMDF WDF定義的接口？謝謝

從您的驅動程序的NDIS方面，你可以撥打NdisMGetDeviceProperty獲得單個微型端口的FDO。從那裏，以通常的方式撥打IoCallDriver（或IoSynchronousCallDriver保存幾行代碼）以發出IRP_MN_QUERY_INTERFACE。

您需要確保在MiniportHalt完成之前取消引用總線接口。
