dev_mc_flush(9)

💅 dev_mc_flush — like, the multicast flush one?

Ok bestie, welcome to the dev_mc_flush page from the Kernel API Manual ✨. It's a tiny one — a little snack of a function — but we're gonna give it the full main-character treatment anyway.

---

✨ SYNOPSIS ✨

void dev_mc_flush (struct net_device *dev );

Literally that's it. No return value, no drama, no nothing. void in, void out, iconic behavior.

---

🫶 ARGUMENTS 🫶

• dev — the device. That's the whole vibe. It's the struct net_device * you're handing over to get its multicast situation cleared out 💖.

---

🌸 DESCRIPTION 🌸

Flush multicast addresses.

Yeah, that's genuinely the entire description bestie 😭. It does exactly what it says on the tin — it flushes the multicast addresses. No cap, no hidden lore, no extra paragraphs. Short king of a manpage 👑.
