netdev_from_priv(9)

💅 netdev_from_priv — kernel API manual, but make it make sense

okay so bestie, welcome to the netdev_from_priv(9) page 💖 this is one of those tiny little kernel helpers that's literally doing the "you dropped this 👑" move — you hand it some private data, it hands you back the network device that data belongs to. that's it. that's the whole vibe. no cap.

---

✨ NAME ✨

netdev_from_priv — get network device from priv 🌸

like, the name is the plot. it's giving "reverse lookup but make it networking."

---

🦋 SYNOPSIS 🦋

struct net_device * netdev_from_priv (const void *priv );

one function, one argument, returns a pointer to a struct net_device. clean, minimal, iconic. ✨

---

🎀 ARGUMENTS 🎀

• priv — network device private data 💜 so like, the little blob of per-device stuff that lives behind the scenes. you pass it in, the function knows what to do with it.

---

🔥 RETURN 🔥

the net_device to which priv belongs 🫶

yep — it gives you back the device that the private data is attached to. no extra lore, no caveats listed here, just the return value doing its one job. periodt.

ngl bestie this page is short, but that's a flex not a flaw — the small ones are always the most useful 😭
