💅 phy_init_eee(9) — like, the EEE glow-up page

okay bestie, welcome to the Kernel API Manual ✨ today's main character is phy_init_eee(9), and no cap, she's the one who checks whether your PHY is down with Energy-Efficient Ethernet. let's get into it 🎀

🌸 NAME 🌸

phy_init_eee — literally inits and checks the EEE feature. both. she multitasks 💅

✨ SYNOPSIS ✨

int phy_init_eee (struct phy_device *phydev , bool clk_stop_enable );

🦋 ARGUMENTS 🦋

  • phydev — the target phy_device struct, iykyk. this is your PHY's whole identity 🫶
  • clk_stop_enable — a bool; it's giving "the PHY is allowed to stop the clock during LPI" energy ⏰

💖 DESCRIPTION 💖

so what she does is: she checks if Energy-Efficient Ethernet (EEE) is even supported, and she does that by snooping on the MMD registers 3.20 and 7.60/61 👀🔍

then — and this is the slay part — she programs MMD register 3.0, setting the "Clock stop enable" bit if required. periodt. that's the whole vibe 🧚

🔥 SEE ALSO 🔥

bestie she has SO many friends, honestly iconic networking behavior 🌈 and heads up, she lives in the kernel file ./drivers/net/phy/phy.c — go say hi 🫶

ngl bestie, that's a lot of cross-references — she's highkey the social butterfly of ./drivers/net/phy 💀💜

✨ that's the page!! ✨ huge thanks to the ./drivers/net/phy source, dated October 2026 — mwah, love u, bye 🍓👑💖
