💖 atl1e_change_mtu(9) — the Kernel API Manual glow-up ✨

okay so bestie, you're looking at atl1e_change_mtu from the kernel API manual (section 9, iykyk), and honestly? it's a little guy with one job and he does it. let's get into it 🎀

---

✨ NAME ✨

atl1e_change_mtu — literally just: Change the Maximum Transfer Unit. that's the whole vibe. MTU glow-up arc 💅

---

🦋 SYNOPSIS 🦋

int atl1e_change_mtu (struct net_device *netdev , int new_mtu );

it takes two things and gives you back an int. slay. no cap.

---

🌸 ARGUMENTS 🌸

• netdev — the network interface device structure 🫶 like, the actual device you're messing with.
• new_mtu — the new value for the maximum frame size. it's giving "make the packets bigger (or smaller) bestie" ⭐

---

💜 DESCRIPTION 💜

Returns 0 on success, negative on failure. that's it. that's the description. short king behavior honestly 👑 but fr fr that's the whole contract: 0 = we ate, negative = it did NOT go well 😭

no extra lore here, bestie — the manpage is short and I'm not about to invent details for you. we keep it factual in this house 💀
