igb_setup_copper_link(9)

💅 igb_setup_copper_link(9) — a Kernel API Manual moment

okay bestie, welcome to the Kernel API Manual page for igb_setup_copper_link, and ngl this one is lowkey cute: it's the little function that gets your copper link together 💖

---

✨ NAME ✨

igb_setup_copper_link — configure copper link settings 🎀

---

🌸 SYNOPSIS 🌸

s32 igb_setup_copper_link (struct e1000_hw *hw );

---

🦋 ARGUMENTS 🦋

• hw — pointer to the HW structure 🫶 (yes queen, hand over the hardware struct, that's the whole vibe)

---

⭐ DESCRIPTION ⭐

so the way this works is: it calls the appropriate function to configure the link for auto-neg or forced speed and duplex 😌 then we check for link — and the second link is established, the calls to configure collision distance and flow control go out. main character energy, fr fr 🔥

if link is not established? we return -E1000_ERR_PHY (-2). that's it, that's the whole mood. 💀
