u64_to_ether_addr(9)

🦋 u64_to_ether_addr(9) 🦋

okay so this is a page straight out of the Kernel API Manual, bestie — welcome to the etherdevice cinematic universe 💅

---

✨ NAME ✨

u64_to_ether_addr — converts a u64 into an Ethernet address. that's it, that's the whole vibe 🎀

---

✨ SYNOPSIS ✨

void u64_to_ether_addr (u64 u , u8 *addr );

---

✨ ARGUMENTS ✨

• u — the u64 you're converting into an Ethernet MAC address 🫶
• addr — a pointer to a six-byte array that's gonna contain the Ethernet address 🌸

lowkey important: addr has to point at a six-byte array, no cap. that's the exact size it expects 💀

---

✨ SEE ALSO ✨

it lives in the kernel file ./include/linux/etherdevice.h and honestly it has SO many siblings, it's giving huge family energy 👑
