eth_zero_addr(9)

✨ eth_zero_addr(9) — the "assign zero address" girlie 💅

okay so this is a kernel API manual page, bestie, and it's about eth_zero_addr — yes the whole page is named after the function, she's the main character fr fr 🎀

---

🌸 NAME 🌸

eth_zero_addr — Assign zero address. that's it, that's the vibe. short, sweet, iconic.

---

⭐ SYNOPSIS ⭐

void eth_zero_addr (u8 *addr );

like, it returns void (nothing back, no thoughts head empty) and takes one pointer named addr 🦋

---

🎀 ARGUMENTS 🎀

• addr — Pointer to a six-byte array containing the Ethernet address. so it's pointing at six whole bytes of Ethernet address energy, and you're handing it over 💖

---

💜 DESCRIPTION 💜

Assign the zero address to the given address array. that's the whole job, no cap — it zeroes out that address array you passed in. lowkey the simplest glow-up in the whole kernel 🌈
