is_broadcast_ether_addr(9)

🎀 is_broadcast_ether_addr(9) 🎀

okay bestie, welcome to the Kernel API Manual corner 💖 this page is for is_broadcast_ether_addr(9), and it’s literally about checking whether an Ethernet address is the broadcast address ✨

---

🌸 NAME 🌸

is_broadcast_ether_addr — determine if the Ethernet address is broadcast 💅

✨ SYNOPSIS ✨

bool is_broadcast_ether_addr (const u8 *addr );

🫶 ARGUMENTS 🫶

• addr — pointer to a six-byte array containing the Ethernet address 🎀

⭐ RETURN ⭐

true if the address is the broadcast address ✅

🦋 DESCRIPTION 🦋

⚠️ Please note: addr must be aligned to u16.

that’s the important little caveat, bestie — the description is short, but this alignment note is giving main character energy, so do not skip it 😭
