[The TCP chimney offload feature is deprecated and should not be used.]
The following three flowcharts illustrate the algorithm that the offload target must use to process each of the following events:
The offload target receives an in-sequence TCP segment.
NDIS posts one or more receive requests (application-supplied receive buffers) to the offload target's MiniportTcpOffloadReceive function.
The push timer for an offloaded TCP connection expires.
To increase performance, the offload target can complete all filled receive requests--and optionally one partially filled receive request--in a single call to the NdisTcpOffloadReceiveComplete function. For simplicity, this option is not illustrated in the delivery algorithm flowcharts.
After starting the delivery algorithm, the offload target must complete the algorithm.
