igbvf_set_multi(9)

💅 igbvf_set_multi(9) — Kernel API Manual energy ✨

Okay so bestie, welcome to igbvf_set_multi(9) — yes that's the function, and yes the manual name is Kernel API Manual, we're in kernel-land now, no cap 🧚

---

🌸 NAME 🌸

igbvf_set_multi — the multicast and promiscuous mode setter. that's literally her whole job 🎀

---

✨ SYNOPSIS ✨

void igbvf_set_multi (struct net_device *netdev );

like, it returns nothing (void), and it takes exactly one thing. icon behavior tbh 💅

---

🦋 ARGUMENTS 🦋

• netdev — the network interface device structure 🫶 that's it. that's the whole argument list. she's low maintenance.

---

🔥 DESCRIPTION 🔥

so the set_multi entry point gets called whenever the multicast address list gets updated, or whenever the network interface flags get updated. like, either one, bestie — that's the vibe check that summons her ⭐

and what does this routine actually do? she's responsible for configuring the hardware so it handles:

• proper multicast behavior 🌈
• promiscuous mode 👀 (yes that's the real name, I'm not being weird)
• all-multi behavior 💜

that's the whole assignment and she ate, fr fr. no return value to worry about, no error to check, she just configures the hardware and dips 😭

ok and that's the whole page 🫶 go configure that hardware, bestie. promiscuous mode is not a personality trait, but knowing when set_multi fires kind of is 💀

sign-off time: this cutie came from source ./drivers/net/ethernet/intel/i..., dated October 2026, and she'll always be igbvf_set_multi(9) in my heart 👑💖 periodt.
