VOID
NdisCompleteBufferPhysicalMapping(
IN NDIS_HANDLE NdisAdapterHandle,
IN PNDIS_BUFFER Buffer,
IN ULONG PhysicalMapRegister
);

NdisCompleteBufferPhysicalMapping is called by the NIC driver to indicate to the operating system that a physical address mapping is no longer needed.

Parameters

NdisAdapterHandle: Identifies the handle that the NDIS interface library associates with the network interface card.
Buffer: Points to a buffer descriptor.
