NdisMEthIndicateReceiveComplete

NdisMEthIndicateReceiveComplete

VOID
   NdisMEthIndicateReceiveComplete(
       IN NDIS_HANDLE MiniportAdapterHandle
       );

NdisMEthIndicateReceiveComplete notifies NDIS that an Ethernet receive packet, identified in a preceding call to NdisMEthIndicateReceive, has been fully transferred by the NIC so that NDIS can notify the appropriate bound protocols.

Parameters

MiniportAdapterHandle

Specifies the handle originally input to MiniportInitialize.

Comments

After any Ethernet receive indication, a miniport eventually must call NdisMEthIndicateReceiveComplete to indicate the end of the transfer operation over the net, even if a particular packet is accepted by no bound protocol.

NdisMEthIndicateReceiveComplete both indicates the completion of a transfer operation for a receive and notifies any bound protocol that has already consumed the initial indication that it can begin postprocessing the received data.

When a miniport calls NdisMEthIndicateReceiveComplete, NDIS indicates the completion of the receive operation to each such protocol by calling its ProtocolReceiveComplete function.

ProtocolReceiveComplete functions need not operate under the severe time constraints of the corresponding ProtocolReceive functions. However, another receive indication to the ProtocolReceive function can come in while the ProtocolReceiveComplete function is running.

A miniport need not call NdisMEthIndicateReceiveComplete in one-to-one correspondence with its calls to NdisMEthIndicateReceive. That is, a NIC driver can issue a single receive-complete indication for some number of receive indications, particularly when network traffic is high. For example, when a miniport is continually indicating receives from the same source, it might call NdisMEthIndicateReceiveComplete once for every ten indications. On the other hand, a miniport might call NdisMEthIndicateReceiveComplete once for each indication when network traffic is low so that the driver can regain ownership of the memory it allocated for receives promptly.
