NDIS_CLIENT_CHIMNEY_OFFLOAD_TCP_CHARACTERISTICS structure (ndischimney.h)
[The TCP chimney offload feature is deprecated and should not be used.]
The NDIS_CLIENT_CHIMNEY_OFFLOAD_TCP_CHARACTERISTICS structure specifies a protocol or intermediate driver's TCP chimney offload-specific entry points.

Members
Header
The header of the NDIS_CLIENT_CHIMNEY_OFFLOAD_TCP_CHARACTERISTICS structure. The header is formatted as an NDIS_OBJECT_HEADER structure. The NDIS_OBJECT_HEADER structure contains the revision number of the NDIS_CLIENT_CHIMNEY_OFFLOAD_TCP_CHARACTERISTICS structure and the size of the NDIS_CLIENT_CHIMNEY_OFFLOAD_TCP_CHARACTERISTICS structure, including the header, in bytes. The Type member of the header is not significant.
Flags
Reserved for system use.
OffloadType
The chimney offload type. The only allowable value is NdisTcpChimneyOffload, which specifies a TCP chimney.
TcpOffloadSendCompleteHandler
The entry point of the driver's ProtocolTcpOffloadSendComplete function.
TcpOffloadReceiveCompleteHandler
The entry point of the driver's ProtocolTcpOffloadReceiveComplete function.
TcpOffloadDisconnectCompleteHandler
The entry point of the driver's ProtocolTcpOffloadDisconnectComplete function.
TcpOffloadForwardCompleteHandler
The entry point of the driver's ProtocolTcpOffloadForwardComplete function.
TcpOffloadEventHandler
The entry point of the driver's ProtocolTcpOffloadEvent function.
TcpOffloadReceiveIndicateHandler
The entry point of the driver's ProtocolTcpOffloadReceiveIndicate function.
Remarks
To register its TCP chimney offload entry points, a protocol or intermediate driver calls the NdisSetOptionalHandlers function in the context of the ProtocolSetOptions function. To the NdisSetOptionalHandlers function, the protocol or intermediate driver passes a pointer to the NDIS_CLIENT_CHIMNEY_OFFLOAD_TCP_CHARACTERISTICS structure.
