DE SERIALIZED MINIPORT DRIVER

A virtual miniport driver adds a virtual adapter that shows up in the network connections and ipconfig result. Next sections will describe most common NDIS driver types as illustrated in the following simplified diagram: Interfacing with higher-level drivers, such as filter drivers, intermediate drivers, and protocol drivers. To complete a send request, connectionless NDIS 6. You may also leave feedback directly on GitHub. When the miniport driver experiences a resource problem, it cannot return send requests to NDIS for requeuing.

Note that a deserialized miniport driver usually completes send requests in protocol-determined order. Handle originally passed into MiniportInitialize. A deserialized miniport driver should complete send requests in the protocol-determined order. Handle passed into MiniportInitialize.

Serialized drivers rely on NDIS to sequence calls to miniport functions and to manage send queues. Forwards a message to the initiating protocol saying. DpcMiniportHangDpcAdapter. The most common miniport drivers are: Finds an adapter object by name.

Dequeues a work item from the work queue miniporf a logical adapter. Ignoring halt device failure! Handle the PnP start device event. Product feedback Sign in to give documentation feedback.

Deserialized miniport drivers internally queue all incoming send packets rather than using NDIS. A deserialized miniport driver is responsible for network buffer-queue management.

Miniport drivers – Windows drivers | Microsoft Docs

A deserialized miniport driver must meet the following requirements when it interfaces with NDIS:. Indicate received data to bound protocols. Read about this change in our blog post. For more information about porting drivers, see:. You may also leave feedback directly on GitHub. The NDIS wrapper also calls the ProtocolXxx functions for its own purposes or on behalf of lower-level drivers to indicate up received packets, indicate the status of lower-level drivers … NDIS protocols driver sefialized often used to inject or capture packets on the network.

As a result, a deserialized miniport driver can achieve significantly better full-duplex performance than a serialized miniport driver.

The miniport driver sets up the miniprt of data minipogt the NIC and then indicates the presence of the received packet to bound higher-level drivers by calling the appropriate Ndis Xxx function.

Releases ownership of one or more packets. A virtual miniport driver adds a virtual adapter that shows up in the network connections and ipconfig result. An intermediate driver is inserted just above miniport drivers and just below transport protocols in the overall networking protocol stack allowing incoming and outgoing packets filtering, inspection or modification.

Serialized NDIS Miniport Drivers

When the miniport driver experiences a resource problem, it cannot return send requests to NDIS for requeuing. A deserialized miniport driver that supports NDIS 6. A deserialized miniport driver must complete all send requests asynchronously.

The following send and receive operations illustrate the interaction of miniport drivers with NDIS and with higher-level drivers:. This can result in a better full duplex performance.

Connection-oriented miniport drivers are muniport deserialized and a connection must be established between two points before data can be exchanged. To find out more, including how to control cookies, see here: Our new feedback system is built on GitHub Issues. Instead, the miniport driver must queue internally all send requests until sufficient resources are available to send the data.
