The NdisMCoIndicateReceiveNetBufferLists function indicates that the miniport driver received data from the network.
void NdisMCoIndicateReceiveNetBufferLists( IN NDIS_HANDLE NdisVcHandle, IN PNET_BUFFER_LIST NetBufferLists, IN ULONG NumberOfNetBufferLists, IN ULONG CoReceiveFlags );
A handle that identifies a virtual connection (VC). The miniport driver obtained this handle as an input parameter to its MiniportCoCreateVc function, either when a client set up an outgoing call or when the call manager created a VC for a client-registered service access point (SAP) to indicate an incoming-call notification on.
A linked list of NET_BUFFER_LIST structures that the miniport driver allocated.
The number of NET_BUFFER_LIST structures that are in the linked list of structures that NetBufferLists specifies.
Flags that define attributes for the send operation. The flags can be combined with a bitwise OR operation. To clear all of the flags, set this parameter to zero. NdisMCoIndicateReceiveNetBufferLists supports the following flags:
The current IRQL is DISPATCH_LEVEL. For more information about this flag, see Dispatch IRQL Tracking.
The miniport driver reclaims ownership of the NET_BUFFER_LIST structures and any attached NET_BUFFER structures immediately after NdisMCoIndicateReceiveNetBufferLists returns.
A miniport driver typically calls the NdisMCoIndicateReceiveNetBufferLists function from its MiniportInterruptDPC function. When a miniport driver calls NdisMCoIndicateReceiveNetBufferLists, it specifies a list of NET_BUFFER_LIST structures at the NetBufferLists parameter. NDIS then passes the NET_BUFFER_LIST structures to bound protocol drivers.
Miniport drivers must set the SourceHandle member of each NET_BUFFER_LIST structure to the same value as the NdisVcHandle parameter so that NDIS can return the NET_BUFFER_LIST structures to the correct miniport driver.
If a miniport driver calls NdisMCoIndicateReceiveNetBufferLists and clears the NDIS_RECEIVE_FLAGS_RESOURCES flag in the CoReceiveFlags parameter, NDIS returns the NET_BUFFER_LIST structures that NetBufferLists specifies to the miniport driver's MiniportReturnNetBufferLists function. In this case, the miniport driver must not reclaim the NET_BUFFER_LIST structures until NDIS returns the NET_BUFFER_LIST structures to the miniport driver's MiniportReturnNetBufferLists function.
If a miniport driver calls NdisMCoIndicateReceiveNetBufferLists and sets the NDIS_RECEIVE_FLAGS_RESOURCES flag in the CoReceiveFlags parameter, the miniport driver must regain ownership of the NET_BUFFER_LIST structures immediately. In this case, NDIS does not call the miniport driver's MiniportReturnNetBufferLists function to return the NET_BUFFER_LIST structures. Instead, NDIS returns the NET_BUFFER_LIST structures to the miniport driver when NdisMCoIndicateReceiveNetBufferLists returns. The miniport driver should reclaim the NET_BUFFER_LIST structures immediately after NdisMCoIndicateReceiveNetBufferLists returns. To reclaim the NET_BUFFER_LIST structures, a miniport driver can call its own MiniportReturnNetBufferLists function.
If a miniport driver sets the NDIS_RECEIVE_FLAGS_RESOURCES flag in the CoReceiveFlags parameter, the protocol drivers must copy the network data and release the NET_BUFFER_LIST structures to the miniport driver. You should design your miniport drivers with enough preallocated NET_BUFFER_LIST structures to avoid unnecessary copying.
The caller of NdisMCoIndicateReceiveNetBufferLists must properly initialize the NET_BUFFER_LIST structures, the attached NET_BUFFER structures, and any attached memory descriptor lists (MDLs).
