netdev_set_mac_address(9)

💅 netdev_set_mac_address — like, the Kernel API Manual page, bestie 🎀

Okay so picture this: you're deep in the kernel, you're in netdev_set_mac_address(9) territory, and honestly? It's giving "small function, big job." Let's get into it. ✨

---

🌸 NAME 🌸

netdev_set_mac_address — writes the MAC address, and yes, from outside the driver, that's the whole point 🫶

---

✨ SYNOPSIS ✨

int netdev_set_mac_address (struct net_device *ndev , void *p );

That's it. That's the whole signature. Iconic, lowkey. 💅

---

🦋 ARGUMENTS 🦋

• ndev — a pointer to the net_device structure. Your device, your bestie, your main character. 💖
• p — a 6 byte address that's gonna get written as the MAC address. Six whole bytes. That's the entire identity of your NIC, no cap. 🍓

---

🌈 RETURN 🌈

It returns 0 for all conditions. Presently, there is no failure case. Not one. Zero failure energy. It literally cannot fail you, and honestly? We stan a reliable function. 😭🔥

---

👑 DESCRIPTION 👑

So here's the vibe: netdev_set_mac_address is the function you call to initialize the MAC address of the Axi Ethernet core. 🌸

It does this by calling the core specific axienet_set_mac_address — so it's like, the friendly middleman. 💜

And the fun part: this is the function that goes into the net_device_ops structure entry ndo_set_mac_address. Like, it is the entry. Registration slay. ✨

Okay that's the whole page, bestie! 💖 This little gem lives in ./drivers/net/ethernet/xilinx, it's part of the Kernel API Manual, and this particular edition is dated October 2026 — so yeah, she's got a timestamp and everything. Go set some MAC addresses, you absolute icon. 👑🌸✨
