i40e_netdev_to_pf(9)

💖 i40e_netdev_to_pf — bestie edition 🎀

Okay so picture this: you're in the kernel API manual, the i40e section (iykyk), and you just need the PF struct for a netdev you're already holding. That's it. That's the whole function. And honestly? It ate. ✨

The manual page is called i40e_netdev_to_pf, and it lives in section 9 (the kernel API one, the cool section 💅).

🌸 NAME 🌸

i40e_netdev_to_pf — retrieve the PF struct for a given netdev. Lowkey the entire personality of this function, ngl.

---

🦋 SYNOPSIS 🦋

struct i40e_pf * i40e_netdev_to_pf (struct net_device *netdev );

That's the whole signature, bestie. Look at it. So clean. So iconic. 🫶

🎀 ARGUMENTS 🎀

• netdev — the corresponding netdev 💖. Yeah, that's it. That's the argument description. The manpage said it, not me.

---

⭐ DESCRIPTION ⭐

So what does it do? It returns the PF struct for the given netdev. Fr fr, that's the whole description. No cap. Sometimes the function is exactly what it says on the tin and we love that for it. 💅

No tricks, no hidden side quests mentioned here — it gives you back the PF struct for that netdev. Periodt. 👑

the cute sign-off part 🧚

So this page? It's from ./drivers/net/ethernet/intel/i40e, and the date on it is October 2026 ✨. That's the source/version and date info, all folded into one lil bow 🎀. And yes — the footer header-y bit still says i40e_netdev_to_pf(9), because of course it does, it knows its name and it's not changing it 💖.

Bye bestie, go get that PF struct 🌸💜🦋
