ice_repr_ethtool_reset(9)

💅 ice_repr_ethtool_reset — NAME ✨

okay so bestie, this is ice_repr_ethtool_reset(9) from the Kernel API Manual, and it literally does one iconic thing: it triggers a VF reset. that's it, that's the whole vibe. 🎀

---

🌸 SYNOPSIS 🌸

int ice_repr_ethtool_reset (struct net_device *dev , u32 *flags );

like, this is the whole signature, no cap. two args, one int coming back at you. 🦋

---

💖 ARGUMENTS 💖

• dev — the network interface device structure bestie. it's the netdev in question, the main character of this whole operation 👑
• flags — a u32 * pointing at the set of reset flags. yes, it's a pointer, yes, you gotta pass it correctly, no we're not skipping that 🙈

---

🔥 RETURN 🔥

here's the vibe check on what you get back:

• 0 — slay, success, we ate 💅
• -EOPNOTSUPP — this happens when you're using an unsupported set of flags. like, the flags said no ❌
• -EBUSY — this one hits when the VF is not ready for reset. it's giving "girl, not right now" 😭

ngl the return values are doing a lot of the storytelling here — zero means win, negative means the kernel is politely (or not so politely) refusing. fr fr.
