e1000_write_phy_reg_page_hv(9)

💖 e1000_write_phy_reg_page_hv(9) 💖

okay so bestie, welcome to the Kernel API Manual — yes we're literally in the kernel docs rn and it's giving elite hacker girlie energy ✨ This one's about e1000_write_phy_reg_page_hv, and ngl it does exactly what it says on the tin.

---

✨ NAME ✨

e1000_write_phy_reg_page_hv — write an HV PHY register 🦋

---

🌸 SYNOPSIS 🌸

s32 e1000_write_phy_reg_page_hv (struct e1000_hw *hw , u32 offset , u16
data );

like yes she's small, she's cute, she takes hw, offset, and data, and she returns an s32. periodt 💅

---

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure 👑 (the whole hardware vibe lives in here)
• offset — register offset to write to 🎯 like, which slot are we poking
• data — data to write at register offset 🍓 the actual payload, the main character

---

🧚 DESCRIPTION 🧚

So what she does: writes the data to the PHY register at the offset. that's it, that's the whole job, and she ate 🔥

⚠️ but listen — she assumes the semaphore is already acquired and the page is already set. she does NOT do that for you, bestie. you gotta handle that yourself or it's gonna be a whole situation 😭 no cap.
