💖 DESCRIPTION 💖

Okay so the ip_input node type is literally the packet greeter: it takes all received packets and queues them into the IP in input processing subsystem. That's the whole vibe. ✨

🎀 HOOKS 🎀

• An ng_ip_input node accepts any request to connect, regardless of the hook name, as long as the name is unique. No cap, any hook name works — it just has to be one of a kind 🦋

---

🦋 CONTROL MESSAGES 🦋

• This node type supports only the generic control messages.
• Other control messages are silently discarded. Not me being dramatic, that's just what happens 💀

---

🌸 SHUTDOWN 🌸

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

---

🔥 SEE ALSO 🔥

• netgraph(4)
• ngctl(8)

The ng_ip_input node type should probably keep some sort of statistics. Lowkey yeah, it should 😭
