💅 igb_setup_copper_link_82575 💅

okay so bestie, welcome to the Kernel API Manual — yes, the Kernel API Manual, capital letters, very serious business, and today's main character is igb_setup_copper_link_82575. she configures copper link settings and she does it flawlessly. no cap. 🎀

---

✨ NAME ✨

igb_setup_copper_link_82575 — configure copper link settings 🦋

---

🌸 SYNOPSIS 🌸

s32 igb_setup_copper_link_82575 (struct e1000_hw *hw );

like, that's the whole vibe. one pointer in, one s32 out. iconic. ✨

---

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure 🫶 literally just a pointer to the hardware struct, that's the whole thing, she's low maintenance.

---

💖 DESCRIPTION 💖

okay so here's what she actually does, and it's giving main character energy:

• configures the link for auto-neg or forced speed and duplex 🔥
• then we check for link 👀
• once link is established, calls to configure collision distance and flow control are called 💅

that's it, that's the function. auto-neg or forced, check for link, then collision distance + flow control once it's up. periodt. ✨
