💅 phy_eee_rx_clock_stop(9) 💅

okay bestie, so this is a page from the Kernel API Manual (yeah, the Kernel API Manual, we're fancy now 🎀) and it's all about one tiny little function that tells your PHY whether it's allowed to ghost its receive clock. Let's get into it ✨

✨ NAME ✨

phy_eee_rx_clock_stop — configure PHY receive clock in LPI 💤

🦋 SYNOPSIS 🦋

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

literally the whole vibe in two lines, no cap 💅

🌸 ARGUMENTS 🌸

  • phydev — the target phy_device struct, aka the PHY we're talking about 🫶
  • clk_stop_enable — a flag that says whether the clock can be stopped. it's giving "yes queen, power that down" or "no ma'am, keep it running" 😭

👑 DESCRIPTION 👑

So what this does is configure whether the PHY can disable its receive clock during LPI mode. that's it, that's the whole job 💖

and if you wanna read up on the receipts, it points you at IEEE 802.3 sections 22.2.2.2, 35.2.2.10, and 45.2.3.1.4. iykyk 📚

⭐ RETURN ⭐

0 or negative error. slay when it's 0, sad girl hours when it's negative 😭
