eth_mac_addr(9)

💅 eth_mac_addr(9) — like, the Kernel API Manual page, bestie

okay so real talk, this is a page from the Kernel API Manual and it's called eth_mac_addr(9). Yes the (9) is the section, no we're not gonna fight about it. Let's go 🌸

---

✨ NAME ✨

eth_mac_addr — set a brand new Ethernet hardware address 👑

---

🦋 SYNOPSIS 🦋

int eth_mac_addr (struct net_device *dev , void *p );

---

🎀 ARGUMENTS 🎀

• dev — the network device in question 🫶
• p — the socket address

---

💖 DESCRIPTION 💖

Change the hardware address of the device. Iconic behaviour, honestly.

Careful though bestie!! This doesn't change hardware matching, so it needs to be overridden for most real devices. Like, it's giving "starter pack function" — do not assume it does the full job on a real device, no cap. 😭
