✨ e1000e_init_rx_addrs — Kernel API Manual, bestie ✨

okay so this is a page from the Kernel API Manual and it's all about e1000e_init_rx_addrs, aka the little function that sets your NIC's receive-address party up 🎀 lowkey important, ngl.

🌸 NAME 🌸

e1000e_init_rx_addrs — Initialize receive address's 💅

(yes the apostrophe is doing whatever it's doing, we don't fix the original, periodt)

⭐ SYNOPSIS ⭐

void e1000e_init_rx_addrs (struct e1000_hw *hw , u16 rar_count );

it returns void, so no return value to obsess over — it just does the thing and dips 🦋

🎀 ARGUMENTS 🎀

  • hw — pointer to the HW structure. it's giving "here's your hardware, go be iconic with it" 👑
  • rar_count — receive address registers. the count, the whole vibe check of how many we're working with 🍓

💖 DESCRIPTION 💖

okay so the actual tea: e1000e_init_rx_addrs sets up the receive address registers. the way it does it is twofold and honestly kind of elegant:

  1. it sets the base receive address register to the device's MAC address (main character energy, obvi 💅)
  2. it clears all the other receive address registers to 0 (not me wiping the whole friend group to zero 😭)

that's it. that's the function. reset the squad, crown the MAC address, slay. ✨

ngl this page is short but she's booked and busy — everything above is literally all of it, no details left behind, pinky promise 🫶

and that's the whole thing!! mwah 💋 this cutie came from ./drivers/net/ethernet/intel/e... (yes the path is truncated in the footer, we don't gatekeep, we just report it faithfully 🙈) and she's dated October 2026 — future queen behavior 👑✨ bye bestie, go init some rx addrs 💜
