✨ igc_init_rx_addrs(9) ✨

okay so bestie, welcome to the Kernel API Manual entry for igc_init_rx_addrs — yes that's the whole title, and yes it's giving "networking girlie does hardware setup" 💅 buckle up 🦋

---

🌸 NAME 🌸

igc_init_rx_addrs — initialize receive addresses, that's literally the whole vibe 🎀

---

⭐ SYNOPSIS ⭐

void igc_init_rx_addrs (struct igc_hw *hw , u16 rar_count );

like, no return value, it just goes and does the thing 🔥

---

💖 ARGUMENTS 💖

• hw — pointer to the HW structure. your main character struct fr, it's the hardware we're talking to 💫
• rar_count — receive address registers. yeah that count, the number of them, iconic 👑

---

🧚 DESCRIPTION 🧚

so what does this actually do? Setup the receive address registers, bestie. it sets the base receive address register to the device's MAC address ✨ and then it clears all the other receive address registers to 0.

that's it. that's the function. base one gets the MAC, everything else gets zeroed out 🫶 no cap, clean slate, slay 💅

lowkey this page shipped out of ./drivers/net/ethernet/intel/igc in October 2026 💜 and that's the whole manual page, bestie — go forth and initialize those receive addresses ✨👑💖
