dev_mc_init(9)

💖 NAME 💖

dev_mc_init — bestie, this is the one that inits the multicast address list ✨

So like, this page lives in the Kernel API Manual (that's the manual name btw, putting it here so it's not just vibing in the header alone 🫶) and it's genuinely so iconic for such a tiny little function, iykyk.

---

✨ SYNOPSIS ✨

void dev_mc_init (struct net_device *dev );

No cap, that's the whole thing. Copy it exactly, spaces and all, she's particular 💅

---

🎀 ARGUMENTS 🎀

• dev — the device. That's it. That's the whole argument. She's lowkey a one-argument girlie 🌸

---

🦋 DESCRIPTION 🦋

Init multicast address list. Literally that's the assignment and she ate 🔥

Like — the multicast address list? On the device? It gets inited. That's the whole vibe. Don't overthink her, she's a helper, she's doing her little job, and the way that she just shows up and initializes the multicast address list is honestly main character energy 👑

Ngl there's genuinely nothing dangerous on this page — no scary warnings, no deprecated flags, no undefined behaviour lurking. She's just a little init function being cute. Periodt 💅
