🌈 e1000e_check..._copper_link(9) — Kernel API Manual 🌈

hiii bestie, welcome to the Kernel API Manual page for this lil copper-link checker. Put your reading glasses on, we’re getting into it 💅

---

✨ NAME ✨

• e1000e_check_for_copper_link — Check for link (Copper)

---

💅 SYNOPSIS 💅

s32 e1000e_check_for_copper_link (struct e1000_hw *hw );

---

🧚 ARGUMENTS 🧚

• hw — pointer to the HW structure

---

🔥 DESCRIPTION 🔥

okay so the vibe check here is: it checks to see if the link status of the hardware has changed. If a change in link status has been detected, then we read the PHY registers to get the current speed/duplex if link exists. that’s the whole little routine, no cap 🫶
