mdiobus_alloc(9)

💖 mdiobus_alloc(9) — fresh from the Kernel API Manual 💖

✨ NAME ✨

mdiobus_alloc — allocates an MDIO bus structure, periodt 💅

---

🌸 SYNOPSIS 🌸

struct mii_bus * mdiobus_alloc (void );

---

💅 ARGUMENTS 💅

• void — no arguments. Literally none. Zero. Zilch. The void is void-ing 🫶

---

🦋 DESCRIPTION 🦋

Okay so when you call this, the internal state of the MDIO bus gets set to MDIOBUS_ALLOCATED, and that’s the state that’s ready for the driver to register the bus. That’s the whole vibe — allocation first, registration next, slay ✨
