💅 igb_clear_vfta(9) — bestie's guide to wiping the VLAN filter table 💅

okay so this is a page from the Kernel API Manual, and honestly? It's a tiny little icon and I'm obsessed. Let's get into it 🫶

✨ NAME ✨

igb_clear_vfta — Clear VLAN filter table 🌸

---

🎀 SYNOPSIS 🎀

void igb_clear_vfta (struct e1000_hw *hw );

that's it. that's the whole call. no cap, it's literally one line 💅

---

🦋 ARGUMENTS 🦋

• hw — pointer to the HW structure 🧚 (yes bestie, the hardware struct, the main character of this whole function)

---

⭐ DESCRIPTION ⭐

So what does she do? She clears the register array which contains the VLAN filter table 💖

And how? By setting all the values to 0. every single one. gone. zeroed. it's giving fresh start, it's giving blank slate, it's giving "not a single VLAN filter left in this house" 💀

that's the whole vibe check: array in → zeroes out. periodt. 🔥
