ks8851_write_mac_addr(9)

🌸 NAME 🌸

ks8851_write_mac_addr — write mac address to device registers

okay so this is the ks8851_write_mac_addr(9) page from the Kernel API Manual, and it is lowkey giving “tiny but important kernel helper” energy 💅✨

---

✨ SYNOPSIS ✨

int ks8851_write_mac_addr (struct net_device *dev );

---

🎀 ARGUMENTS 🎀

• dev — the network device. that’s the whole argument, bestie, and she’s iconic for it 🫶

---

💅 DESCRIPTION 💅

It updates the KS8851 MAC address registers from the address in dev. literally just “take the address sitting in dev and write it where it needs to go” ✨

Heads up though: this call assumes the chip is not running, so there is no need to shutdown the RXQ process whilst setting this. like, that’s the vibe it expects — chip not running, RXQ process not needing a shutdown, no drama 😌💖
