igc_change_mtu(9)

✨ NAME ✨

Okay bestie, welcome to igc_change_mtu(9) from the Kernel API Manual — this page is all about igc_change_mtu and its whole thing is Change the Maximum Transfer Unit. 💅✨

🦋 SYNOPSIS 🦋

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

🎀 ARGUMENTS 🎀

• netdev — the network interface device structure, aka the main character handing you the device info 🫶
• new_mtu — the new value for maximum frame size, literally the new MTU vibe check ⭐

🌸 DESCRIPTION 🌸

So the function does what it says on the tin: it returns 0 on success, and a negative value on failure. No cap, that's the whole behavioral contract — 0 means slay, negative means something went sideways 😭💀

🔥 SEE ALSO 🔥
