ks8851_init_mac(9)

✨ ks8851_init_mac ✨

okay bestie, welcome to the ks8851_init_mac page from the Kernel API Manual — yes that's the manual name, we're folding it in up top so it doesn't get lonely 💅 this one's a little function with one job and she does it flawlessly, no cap.

---

💖 NAME 💖

ks8851_init_mac — initialise the mac address 🎀

---

🦋 SYNOPSIS 🦋

void ks8851_init_mac (struct ks8851_net *ks , struct device_node *np );

like, that's it. that's the whole signature. she's void, she returns nothing, she just does the thing ✨

---

🌸 ARGUMENTS 🌸

• ks — the device structure, aka the main character of this whole ks8851 saga 👑
• np — the device node pointer 🧚

---

🔥 DESCRIPTION 🔥

okay so here's the vibe: this function gets or creates the initial mac address for the device, and then sets that bad boy into the station address register. simple. iconic. done. 💅

and the searching order? it's giving priority list, so pay attention:

1. a mac address supplied in the device tree takes precedence — device tree says jump, we say how high 🌈
2. otherwise, if there is an EEPROM present, then we try that one 🍓
3. if no valid mac address is found, we use eth_random_addr to create a new one — random era, truly main character energy 😭

so like, worst case scenario you still get a mac address. she never leaves you empty-handed. 🫶
