💅 igc_update_mc_addr_list(9) — Kernel API Manual 💅

💖 NAME 💖

igc_update_mc_addr_list — update Multicast addresses. Okay so this is the one that refreshes the whole multicast situation, bestie. Slay.

✨ SYNOPSIS ✨

void igc_update_mc_addr_list (struct igc_hw *hw , u8 *mc_addr_list , u32
       mc_addr_count );

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure. Like, the hardware bestie in question 💅
• mc_addr_list — array of multicast addresses to program
• mc_addr_count — number of multicast addresses to program

🌸 DESCRIPTION 🌸

Bestie, this literally updates the entire Multicast Table Array. Not a little corner of it. The whole thing. ✨

The caller must have a packed mc_addr_list of multicast addresses. No cap. That part is non-negotiable, so make sure it’s packed before you come through. 🫶
