axienet_set_mac_address(9)

💅 axienet_set_mac_address(9) — from the Kernel API Manual, bestie

okay so imagine you're deep in the kernel docs (the Kernel API Manual, no less) and you land on this one. it's short, it's sweet, it's giving "one job, does it well." let's get into it 🎀

---

✨ NAME ✨

axienet_set_mac_address — writes the MAC address. that's it, that's the whole vibe. she writes the MAC address 💖

---

🦋 SYNOPSIS 🦋

void axienet_set_mac_address (struct net_device *ndev , const void *address );

returns nothing (void), takes two things, slays. periodt.

---

🌸 ARGUMENTS 🌸

• ndev — a pointer to the net_device structure. you know her, you love her.
• address — the 6 byte address that's getting written as the MAC address. six bytes, no more, no less, fr fr.

---

💜 DESCRIPTION 💜

so this function gets called to initialize the MAC address of the Axi Ethernet core. that's the whole main character moment ✨

how does she do it? she writes to the UAW0 and UAW1 registers of the core. those two registers, that's where the magic happens. iconic behaviour, no cap 🔥

lowkey the shortest manpage ever and honestly? she ate. go read the rest of them, iykyk 🫶
