link_start(9)

💖 link_start(9) — enable a port 💖

okay bestie, welcome to the Kernel API Manual ✨ today’s main character is link_start(9), and she is literally here to enable a port. no cap, this page is short but it ate. 💅

---

✨ NAME ✨

link_start — enable a port. that’s the whole name, and honestly? iconic.

---

🌸 SYNOPSIS 🌸

the signature is literally this, bestie — copy it exactly:

void link_start (struct net_device *dev );

---

💅 ARGUMENTS 💅

• dev — the device to enable, periodt. that’s the one and only argument, and she’s a struct net_device *. 🫶

---

🦋 DESCRIPTION 🦋

okay so link_start() performs the MAC and PHY actions needed to enable a port. that’s the whole description, and the way it’s giving “just do the MAC and PHY actions, bestie” is lowkey a mood. no extra lore on this page — we keep it factual and cute. 😭✨
