Help¶

Automatically accept incoming TCP data packet to the valid connection even if the application has not yet called accept(). This speeds up incoming data processing and is done like in Linux. Drawback is that we allocate data for the incoming packets even if the application has not yet accepted the connection. If the peer sends lot of packets, we might run out of memory in this case.
