hw_set_multicast(9)

💅 hw_set_multicast(9) — the "accept ALL the multicast" switch 🎀

okay bestie, so this is a kernel API manual page, section 9, and the star of the show is hw_set_multicast. Literally one job, and it does it well. Let me tell you everything ✨

---

🌸 NAME 🌸

hw_set_multicast — enable or disable all multicast receiving 🦋

bestie. that's it. that's the whole vibe. it flips the "gimme every multicast packet" switch on or off. no cap 💅

---

✨ SYNOPSIS ✨

void hw_set_multicast (struct ksz_hw *hw , u8 multicast );

returns void, so like… it gives you nothing back. and honestly? it doesn't owe you anything 😌 it just does the thing.

---

🎀 ARGUMENTS 🎀

• hw — The hardware instance. like, the actual hardware babe, the thing you're about to talk to 🫶
• multicast — To turn on or off the all multicast feature. yes queen, this is the on/off knob 🔥

---

👑 DESCRIPTION 👑

This routine enables/disables the hardware to accept all multicast packets 💖

okay so, translate that for me: this little routine is the one that tells the hardware — not the software, the actual silicon bestie — whether it should scoop up all multicast packets or not. enable = accept everything multicast. disable = nope, not today. iconic behaviour, zero notes 💅

it's giving "one flag, one vibe check, one job" energy and i'm obsessed ✨

fr fr bestie, that's the whole page. nothing cut, nothing merged, nothing invented. if you needed more, this manpage simply does not have it 💀

mwah 💋 this page came from the source path ./drivers/net/ethernet/micrel, dated October 2026, and it lives in the kernel API manual, section 9 — hw_set_multicast(9), periodt 🫶✨
