igb_change_mtu(9)

💖 igb_change_mtu(9) 💖

okay so bestie, welcome to the Kernel API Manual (section 9, we love a numbered section, very demure) — this little page is all about igb_change_mtu, and yes it does exactly what it says on the tin: it changes the Maximum Transfer Unit. iconic behaviour honestly 🎀

---

✨ NAME ✨

igb_change_mtu — Change the Maximum Transfer Unit 🌈

---

🦋 SYNOPSIS 🦋

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

like... that's the whole call. two args. no cap. 💅

---

🌸 ARGUMENTS 🌸

• netdev — the network interface device structure, aka the whole entire vibe of the device you're messing with 🫶
• new_mtu — the new value for the maximum frame size, i.e. the glow-up number you're assigning ✨

---

👑 DESCRIPTION 👑

Returns 0 on success, negative on failure. that's it. that's the whole description. short and sweet, main character energy fr fr 💀

lowkey obsessed with how a whole manpage can be three sentences and still slay. anyway — 0 good, negative bad. screenshot it. 🍓

and now the full friend group — every single one of these, no skips, no cuts, we're listing them all because they're all part of the family 😭💖
