IPv4 input netgraph node

## NAME

**ng\_ip\_input** – IPv4 input netgraph node

## SYNOPSIS

**#include \<netgraph/ng\_ip\_input.h\>**

## DESCRIPTION

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.

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.
