igbvf_change_mtu(9)

💖 igbvf_change_mtu(9) 💖

okay so bestie, we're deep in the Kernel API Manual today, and the main character is literally igbvf_change_mtu(9). It's giving "small function, very specific job, no cap." 🦋

---

✨ NAME ✨

igbvf_change_mtu — Change the Maximum Transfer Unit. That's the whole vibe. 💅

---

🌸 SYNOPSIS 🌸

The signature, character-for-character, because we do not play with code:

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

---

🎀 ARGUMENTS 🎀

• netdev — the network interface device structure. It's the device bestie we're doing this for. 🫶
• new_mtu — the new value for maximum frame size. Fresh value, fresh frame energy. ✨

---

💜 DESCRIPTION 💜

Returns 0 on success, negative on failure. That's it, that's the function. No extra lore, no secret side quest. 💀

---

🔥 SEE ALSO 🔥

Kernel file ./drivers/net/ethernet/intel/igbvf/netdev.c — yes, that exact path, don't @ me.
