Therefore, driver vendors cannot assume that the interface that they send traffic to is implemented by the last driver in the chain. Unsourced material may be challenged and removed. A completion call does not necessarily indicate that a packet has been transmitted; however, with the exception of intelligent NICs, the packet usually has been transmitted. For more information, you can refer this msdn link. The miniport driver can specify the send window dynamically and on a per-line basis by calling NdisMIndicateStatus with a line-up indication.

For Windows and later drivers, this points to a registry path, which is opaque to any NDIS driver that exports ndis 5.1 miniport MiniportXxx functions. For more information, you can refer this msdn link. Office Office Exchange Server. The “PassThru” sample is ndis 5.1 miniport good starting point for intermediate drivers as it implements all the necessary details required in this driver type, but just passes the traffic through minpiort the next driver in the chain.
Furthermore, it is possible miniporrt simulate several virtual NICs by implementing virtual miniport drivers that send and receive traffic from a single physical NIC.

In practice, intermediate drivers implement both miniport and protocol interfaces. This article needs additional citations for verification.
Network Driver Interface Specification – Wikipedia
The device class-specific driver models are typically structured as a port driver written by Microsoft paired with a miniport driver written by an independent hardware vendor. Since wireless drivers involve lot of complex memory operations and important cases, it is required to understand the actual NDIS 5. But it does not have the same parameter like NDIS 5.
This website is using cookies. A completion call does, however, indicate that the miniport driver is ready to release ownership of the packet.
Pointer to a system-supplied parameter. For Windows and later drivers, this points to ndis 5.1 miniport driver object, which is opaque to any NDIS driver that exports minioort MiniportXxx functions.
Therefore, the NDIS acts as the interface between the media access control MAC sublayer, which is the lower sublayer of the data link layer, and the network layer layer 3.

Views Read Edit View history. This means that traffic coming into the miniport may be received in parallel by several protocol drivers. Below is the sample code snippets to register NDIS 6.
