update_mtu(9)

✨ NAME ✨

update_mtu — API to inform the change in the mtu.

Okay so this is the update_mtu(9) page from the Kernel API Manual, and it is literally here so you can inform the change in the mtu. That's the whole assignment, bestie 💅

🎀 SYNOPSIS 🎀

The signature, character for character:

int update_mtu (struct qed_dev *cdev , u16 mtu );

🌸 ARGUMENTS 🌸

• cdev — Qed dev pointer. That's the qed dev pointer you're handing over, bestie 🫶
• mtu — MTU. Just the MTU, periodt.

💖 RETURN 💖

Int. — that's the return, no cap. It literally says Int. and nothing else, so we are not inventing extra lore here 🙈
