💅 arc_emac_set_address(9) 💅

okay so bestie, welcome to the Kernel API Manual — this one's all about arc_emac_set_address, and honestly? It's giving "small function, big responsibility." Let's get into it 🫶

✨ NAME ✨

arc_emac_set_address — sets the MAC address for this device. That's it, that's the whole vibe. 💖

🌸 SYNOPSIS 🌸

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

🎀 ARGUMENTS 🎀

  • ndev — a pointer to the net_device structure. yep, the whole device situation 🔥
  • p — the 6 byte address that's gonna be written as the MAC address. six bytes, no cap 💀

🦋 DESCRIPTION 🦋

so what does it actually do? This function copies the HW address from the sockaddr structure over to the net_device structure — and then it updates the address in HW too. so it's not just, like, a fake-out in software, it's doing the real thing ✨ literally updating the hardware address, main character energy 👑

⭐ RETURN ⭐

  • -EBUSY — if the net device is busy 😭 (it's booked and busy, try again later)
  • 0 — if the address is set successfully 🎉 slay
