💅 ether_addr_to_u64

okay bestie, welcome to the Linux Kernel API Manual ✨ this one's a tiny little icon, and honestly? it eats. no cap.

🌸 NAME

ether_addr_to_u64 — Convert an Ethernet address into a u64 value. that's it. that's the whole job. she takes your MAC and hands you back one chunky 64-bit number 💖

---

🦋 SYNOPSIS

u64 ether_addr_to_u64 (const u8 *addr );

---

🎀 ARGUMENTS

• addr — Pointer to a six-byte array containing the Ethernet address. six bytes, bestie. count 'em. that's the whole vibe check right there 👑

---

⭐ RETURN

a u64 value of the address 🔥 — lowkey just your ethernet address but in Big Number form
