💅 e1000_rar_set_pch2lan — Kernel API Manual, bestie edition ✨

okay so picture this: you're deep in the e1000 driver, the manual page name is literally e1000_rar_set_pch2lan(9), and you just need to set a receive address register. no cap, that's the whole vibe. let's get into it 🫶

---

🌸 NAME 🌸

e1000_rar_set_pch2lan — Set receive address register</p> 💖

---

✨ SYNOPSIS ✨

int e1000_rar_set_pch2lan (struct e1000_hw *hw , u8 *addr , u32 index );

like yes she takes three things and gives you back an int, iconic behavior honestly 💅

---

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure 🧚 like, the whole hardware situation
• addr — pointer to the receive address 💌 the address itself, pointing at it
• index — receive address array register 🗂️ which slot in the array we're talking about

---

🦋 DESCRIPTION 🦋

So what she does: sets the receive address array register at index to the address passed in by addr. clean, simple, no drama 🌈

but here's the tea for 82579 ☕ — RAR[0] is the base address register that is to contain the MAC address, but RAR[1-6] are reserved for manageability (ME). so like, don't touch those, they're taken 🙈. use SHRA[0-3] in place of those reserved for ME instead. periodt. 👑
