e1000_reconfigure_k1_params(9)

💅 e1000_reconfigure_k1_params — Kernel API Manual

okay so bestie, we're in the e1000_reconfigure_k1_params(9) page of the Kernel API Manual, and honestly? It's a short one. But it's iconic in its own little way. Let's get into it ✨

---

🎀 NAME

e1000_reconfigure_k1_params — reconfigure Kumeran K1 parameters. That's it. That's the whole vibe.

---

🌸 SYNOPSIS

s32 e1000_reconfigure_k1_params(struct e1000_hw *hw);

---

🦋 ARGUMENTS

• hw — pointer to the HW structure 💖 literally just a pointer to your hardware struct, she's the main character here.

---

✨ DESCRIPTION

so here's the tea ☕ — by default, K1 is enabled after a MAC reset. Which means this function doesn't have to turn it on. Nope! It only disables it. That's the whole job. Lowkey efficient, highkey slay. 💅

---

🔥 CONTEXT

⚠️ bestie, listen to me: the PHY semaphore must be held by the caller. That's not a suggestion, it's the rules. Hold the semaphore or don't call her at all, fr fr 🙈

---

⭐ RETURN

• 0 on success 🫶
• negative on failure 😭

later bestie 💜 this page came from ./drivers/net/ethernet/intel/e..., dated October 2026, and it's filed under e1000_reconfigure_k1_params(9). go hold that semaphore. mwah 🫶✨
