idpf_change_mtu(9)

✨ NAME ✨

idpf_change_mtu is the NDO callback to change the MTU, bestie 💅 — and this lil icon lives in the Kernel API Manual, section 9. No cap, she's here to handle the MTU glow-up.

🦋 SYNOPSIS 🦋

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

🎀 ARGUMENTS 🎀

• netdev — the network interface device structure. She's the whole interface vibe 🫶
• new_mtu — the new value for maximum frame size. Fresh number, fresh frame energy ✨

💖 DESCRIPTION 💖

Okay so the description is short and iconic: returns 0 on success, negative on failure. That's it, that's the whole mood. 💀✨

Lowkey a tiny function, but bestie, the return value is doing main character work.
