A deserialized NDIS miniport driver serializes the operation of its own MiniportXxx functions and queues internally all send requests rather than relying on NDIS to perform these functions. They are typically layered between miniport adapters and protocol bindings and offer the same packets filtering, inspection or modification capabilities. Finds an adapter object by name. Versions starting from 2. At its upper edge, the miniport driver exposes a standard NDIS miniport driver interface, which enables the miniport driver to communicate with overlying NDIS drivers.

The deserialized driver model is the default model for NDIS miniport drivers.
Handle the PnP stop device event. The miniport driver sets up the transfer of setialized from the NIC and then indicates the presence of the received packet to bound higher-level drivers by calling the appropriate Ndis Xxx function.
Instead, the miniport driver must queue send requests internally until sufficient resources are available to transmit the data. By continuing to use this website, you agree to their use.
Serialized NDIS Miniport Drivers
Forwards a message to the initiating protocol saying. Releases resources allocated by a call to NdisInitializeWrapper. A deserialized miniport driver must protect its network buffer queues with spin locks. No upper miinport layer. The later is a small piece of code surrounding all types of the NDIS device drivers.
A deserialized NDIS miniport driver serializes the operation of its own MiniportXxx functions and queues internally all send requests rather than relying on NDIS to perform these functions. Connection-oriented miniport drivers are always deserialized and a connection must be established between two points before data can be exchanged. NDIS supports miniport drivers miniort both connectionless environments and connection-oriented environments.
Serialized NDIS Miniport Drivers – Windows drivers | Microsoft Docs
Queues a work item for execution at a later time. Determines whether a packet has the same destination address as an adapter. Interfacing with higher-level drivers, such as filter drivers, intermediate drivers, and protocol drivers. A deserialized miniport driver must identify itself as such to NDIS during initialization.
Internal callback for handling bugchecks – calls adapter’s shutdown handler. NextDeviceObjectIrp.
Next sections will describe most common NDIS driver types as illustrated in the following simplified diagram:. Our new feedback system is built on GitHub Issues.
Checks seralized see if the miniport is hung. To complete a send request, connectionless NDIS 6. Next sections will describe most common NDIS driver types as illustrated in the following simplified diagram: Choose the type you’d like to provide: However, a miniport driver that supports packet priority for example, IEEE The NDIS library exports a full set of functions NdisM Xxx and other Ndis Xxx functions that encapsulate all of the operating system functions that a miniport driver must call.
A deserialized miniport driver should complete send requests in the protocol-determined order. Queries a logical adapter for properties. LockOldIrql. Our new feedback system is built on GitHub Issues. A deserialized miniport driver that supports NDIS 6.
Handle originally passed into MiniportInitialize. Handle the PnP start device event. Dequeues a work item from the work queue of a logical serializwd. Deserialized miniport drivers internally queue all incoming send packets rather than using NDIS.
