[The TCP chimney offload feature is deprecated and should not be used.]
NDIS calls a protocol or intermediate driver's ProtocolTcpOffloadSendComplete function to complete a send operation that the driver previously initiated by calling the NdisOffloadTcpSend function.
ProtocolBindingContext [in]A handle to a context area allocated by the protocol driver. The driver maintains the per binding context information in this context area. The driver supplied this handle to NDIS when the driver called the NdisOpenAdapterEx function.
NetBufferList [in]A pointer to a NET_BUFFER_LIST structure. This structure might be stand-alone or the first structure in a linked list of NET_BUFFER_LIST structures. The driver supplied this pointer as an input parameter in a previous call to the NdisOffloadTcpSend function.
In response to an underlying driver's or offload target's call to the NdisOffloadTcpSendComplete function, NDIS calls the overlying protocol driver's or intermediate driver's ProtocolTcpOffloadSendComplete function.
To propagate the completion of the I/O operation to the overlying driver or host stack, the intermediate driver itself calls the NdisOffloadTcpSendComplete function, passing in the following:
In response, NDIS calls the overlying driver's ProtocolTcpOffloadSendComplete function, passing a ProtocolBindingContext handle and the PNET_BUFFER_LIST pointer supplied by the intermediate driver to the NdisOffloadTcpSendComplete function.
