💅 sis900_reset_phy — a Kernel API Manual moment ✨

okay so bestie, buckle up, because we're diving into sis900_reset_phy(9) from the Kernel API Manual and honestly? it's giving "small function, big job" energy 🎀

---

🌸 NAME 🌸

sis900_reset_phy — reset that sis900 mii phy, periodt 💅

---

✨ SYNOPSIS ✨

u16 sis900_reset_phy (struct net_device *net_dev , int phy_addr );

like, that's the whole signature. cute, right? 🫶

---

🦋 ARGUMENTS 🦋

• net_dev — the net device to write 💖 (yes, that's literally what it is, no cap)
• phy_addr — the default phy address 🌸

---

👑 DESCRIPTION 👑

so here's the tea ☕: some specific phy just cannot function properly without a reset. like, it simply refuses. dramatic much? 😭

this function handles that reset, and it gets called in two situations:

1. during initialization 🌈
2. when the link status changes from ON to DOWN 💀

that's it, that's the whole vibe check. simple, iconic, necessary.
