Miniport drivers call the NdisMSendNetBufferListsComplete function to return a linked list of NET_BUFFER_LIST structures to an overlying driver and to return the final status of a send request.
VOID NdisMSendNetBufferListsComplete( _In_ NDIS_HANDLE MiniportAdapterHandle, _In_ PNET_BUFFER_LIST NetBufferLists, _In_ ULONG SendCompleteFlags );
- MiniportAdapterHandle [in]
The miniport handle that NDIS passed to the MiniportInitializeEx function.
- NetBufferLists [in]
A pointer to a linked list of NET_BUFFER_LIST structures. The miniport driver received the NET_BUFFER_LIST structures in previous calls to its MiniportSendNetBufferLists function.
- SendCompleteFlags [in]
NDIS flags that can be combined with an OR operation. To clear all the flags, set this member to zero. This function supports the NDIS_SEND_COMPLETE_FLAGS_DISPATCH_LEVEL flag which; if set, indicates that the current IRQL is DISPATCH_LEVEL. For more information about this flag, see Dispatch IRQL Tracking.
A miniport driver calls NdisMSendNetBufferListsComplete to complete send requests that NDIS made to the driver's MiniportSendNetBufferLists function. The miniport driver specifies a linked list of NET_BUFFER_LIST structures that are associated with the completed send requests. While the status of the send requests is pending, the miniport driver retains ownership of the NET_BUFFER_LIST structures and all the protocol-allocated resources that are associated with the NET_BUFFER_LIST structures.
After a miniport driver calls NdisMSendNetBufferListsComplete, NDIS calls the ProtocolSendNetBufferListsComplete function of the driver that called the NdisSendNetBufferLists function to initiate the send request.
The miniport driver can complete send requests in any order. For example, the miniport driver could concatenate the NET_BUFFER_LIST structure lists from multiple MiniportSendNetBufferLists calls or split up a list from a MiniportSendNetBufferLists call. However, the miniport driver must not modify the list of NET_BUFFER structures that are associated with a NET_BUFFER_LIST structure.
The miniport driver must set one of the following status codes in the Status member of each NET_BUFFER_LIST structure that the NetBufferLists parameter specifies:
All the network data that the NET_BUFFER_LIST structure and the associated NET_BUFFER structures describe was successfully processed for transmission. For example, the miniport driver copied the data to a queue or the data has already been transmitted.
The size of the data in some NET_BUFFER structures associated with this NET_BUFFER_LIST structure was too large for the underlying NIC.
The send request for this NET_BUFFER_LIST structure failed due to insufficient resources.
The miniport adapter is in the Paused state, as described on the reference page for the MiniportPause function.
NDIS called the MiniportCancelSend function to cancel the send operation for this NET_BUFFER_LIST structure.
The miniport driver aborted the send request due to a reset.
The miniport driver failed the send request because of some reason other than those previously described. For example, the miniport driver can fail the send request due to a hardware failure.
A miniport driver's call to NdisMSendNetBufferListsComplete does not necessarily mean that the data for a send request has been transmitted over the network. The data might be queued in the NIC hardware.
