e1000_set_mac(9)

💅 e1000_set_mac(9) — the glow-up edition

okay so bestie, this is the e1000_set_mac(9) page from the Kernel API Manual, and it's a short one but we're gonna treat it with the respect it deserves ✨

---

🎀 NAME

e1000_set_mac — change the Ethernet Address of the NIC 🦋

like… you're literally giving your network card a whole new identity. main character energy fr fr.

---

✨ SYNOPSIS

int e1000_set_mac (struct net_device *netdev , void *p );

that's the whole signature, copied exactly, no notes 💅

---

🌸 ARGUMENTS

• netdev — the network interface device structure 🫶 like the NIC's whole little passport, okay?
• p — a pointer to an address structure 📬 the address situation lives in there

---

💖 DESCRIPTION

Returns 0 on success, negative on failure. periodt. that's it, that's the whole description — she's brief and she knows it 😭💀

so real talk: check the return value, bestie. 0 means slay, negative means it did not slay. no cap.

ngl this page is short, but short is iconic too. 0 = success, negative = not success, and that's the whole vibe check 🧚

and that's the page, bestie 🫶 source is ./drivers/net/ethernet/intel/e..., dated October 2026, and yeah it's still e1000_set_mac(9) — stan forever 💜⭐
