Overview

The ip_input node type takes all received packets and queues them into the IP in input processing subsystem.

Hooks

An ng_ip_input node accepts any request to connect, regardless of the hook name, as long as the name is unique.

Control messages

This node type supports only the generic control messages. Other control messages are silently discarded.

Shutdown

This node shuts down upon receipt of a NGM_SHUTDOWN control message, or when all hooks have been disconnected.
