Detailed Description

State for one TCP listening port.

All queue storage is embedded in this struct so the entire listener pool lives in BSS - no heap allocation anywhere in the listener layer.

A single Listener instance consumes: sizeof(protocore_pcb*) + sizeof(protocore_platform_queue_ctrl) + EVT_QUEUE_DEPTH*sizeof(TcpEvt)

• sizeof(protocore_platform_queue) + 3 bytes overhead (port, proto, active).
