💖 igb_update_mc_addr_list(9) 💖

okay so bestie, welcome to the Kernel API Manual entry for igb_update_mc_addr_list — yes it's a real function, yes it's giving networking main character energy, and yes we're gonna get through it together 🫶

---

✨ NAME ✨

igb_update_mc_addr_list — Update Multicast addresses 🌈

like, it updates multicast addresses. that's the whole vibe. slay.

---

🌸 SYNOPSIS 🌸

void igb_update_mc_addr_list (struct e1000_hw *hw , u8 *mc_addr_list ,
u32 mc_addr_count );

no cap, that's the exact signature — copy it character for character or it won't compile and you'll be sad 😭

---

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure 💅 like, the hardware context, she's the main character here
• mc_addr_list — array of multicast addresses to program 🦋 the actual list, packed and ready
• mc_addr_count — number of multicast addresses to program ⭐ how many of 'em we're doing

---

🔥 DESCRIPTION 🔥

Updates entire Multicast Table Array. the way that it does the whole table and not just a little corner of it — iconic behavior honestly 👑

the caller must have a packed mc_addr_list of multicast addresses. so like, you have to hand her a properly packed list, she's not doing that part for you. iykyk 🙈

fr fr, that "packed" detail is not optional — it's a requirement stated right there in the original, so don't come for me if you skip it 💀
