phy_configure(9)

💅 phy_configure(9) 💅

okay so bestie, welcome to the Kernel API Manual — this is the page for phy_configure(9) and it's literally the glow-up button for your PHY ✨

---

🌸 NAME 🌸

phy_configure — changes the phy parameters 🎀

---

🦋 SYNOPSIS 🦋

int phy_configure (struct phy *phy , union phy_configure_opts *opts );

---

💖 ARGUMENTS 💖

• phy — the phy you got back from phy_get. yes, that one. the whole point 🫶
• opts — the new configuration to apply. the new fit. the new lewk 👑

---

✨ DESCRIPTION ✨

So like — this is the function you call to actually change the PHY parameters. that's the whole vibe 💅

⚠️ but listen: phy_init must have been called on the phy first. no init, no configuring. rules are rules 😭

The configuration gets applied on the current phy mode — and if you wanna be in a different mode, you change that with phy_set_mode first. mode first, config second, always. periodt 💜

---

🔥 RETURN 🔥

0 if successful, a negative error code otherwise 🙈 (so like, check it. please. for me. 🥺)
