igb_vmdq_set_loopback_pf(9)

💅 igb_vmdq_set_loopback_pf(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ this lil page is all about igb_vmdq_set_loopback_pf(9) and honestly? she's short, she's sweet, she flips a switch. let's get into it 🫶

---

🌸 NAME 🌸

igb_vmdq_set_loopback_pf — enable or disable vmdq loopback. that's it. that's the whole job. queen of scope 💅

---

✨ SYNOPSIS ✨

void igb_vmdq_set_loopback_pf (struct e1000_hw *hw , bool enable );

like, no return value, no drama. she just does the thing 🔥

---

🎀 ARGUMENTS 🎀

• hw — pointer to the hardware struct. yeah, the whole hardware situation, handed to you as a pointer 🖥️
• enable — the state to enter, either enabled or disabled. binary queen, no in-between 👑

---

🦋 DESCRIPTION 🦋

enables/disables L2 switch loopback functionality. lowkey iconic that a function this tiny is doing L2 switch loopback work but okay go off 💖

ngl the original says exactly this much and no more, so we're not gonna invent lore. she does loopback. on or off. periodt ✨
