velocity_ethtool_up(9)

💅 velocity_ethtool_up(9)

okay hi bestie!! so this is a page from the Kernel API Manual — it's the man page for velocity_ethtool_up, and honestly it's a short one but she's doing a very important job 🫶

---

✨ NAME ✨

velocity_ethtool_up — pre hook for ethtool 💫

---

🎀 SYNOPSIS 🎀

int velocity_ethtool_up (struct net_device *dev );

---

🌸 ARGUMENTS 🌸

• dev — the network device 🦋 (that's the whole argument list, she travels light)

---

👑 DESCRIPTION 👑

okay so picture this: this function gets called before an ethtool operation runs. before we go poking at the chip, we have to make 💯 sure it's not still chillin' in D3 state — like, she needs to be awake before we start prodding her. ⭐

and here's the cute part: sometimes ethtool ops get nested (yes, like little matryoshka dolls 💀). in that case, we only wake the device up in the outermost block. no double-waking, no chaos. the way that she's responsible… main character energy fr fr 💜

and that's the whole page, bestie — short and sweet like a lil strawberry 🍓✨ this one lives in ./drivers/net/ethernet/via, dated October 2026, and it's velocity_ethtool_up(9) forever and always 💅🎀 no cap, that's a wrap 🫶
