💖 e1000_check_for_serdes_link_82571 💖

okay bestie, welcome to the Kernel API Manual ✨ this is the page for e1000_check_for_serdes_link_82571(9) and it's literally the vibe-check function for your SerDes link 🌈

---

✨ NAME ✨

e1000_check_for_serdes_link_82571 — check for link (Serdes) 🎀

---

🦋 SYNOPSIS 🦋

s32 e1000_check_for_serdes_link_82571 (struct e1000_hw *hw );

that's it, that's the whole call. iconique 💅

---

🌸 ARGUMENTS 🌸

• hw — pointer to the HW structure 🫶 (yes, the whole hardware struct, she's carrying everything)

---

👑 DESCRIPTION 👑

So what does she do? She reports the link state as up or down, periodt. ⭐

If autonegotiation is supported by the link partner, the link state is determined by the result of autonegotiation. And ngl, that is the most likely case 💀 — your partner usually speaks the language.

But if autonegotiation is not supported by the link partner, and the link has a valid signal, then she forces the link up. main character energy, taking matters into her own hands 🔥

The link state is represented internally here by 4 states, and honestly? a whole little arc:

1. down
2. autoneg_progress
3. autoneg_complete — the link successfully autonegotiated 🎉
4. forced_up — the link has been forced up, it did not autonegotiate 💪

no cap, those four states are the entire plot of this function. down → autoneg_progress → either autoneg_complete or forced_up. character development fr fr 🌸
