igb_setup_mrqc(9)

okay bestie, welcome to the igb_setup_mrqc(9) page 💅 this one lives in the Kernel API Manual, and it's short but iconic — let's get into it 🎀

✨ NAME ✨

igb_setup_mrqc — configure the multiple receive queue control registers 🌀

like, it literally sets up the MRQC regs so your receive queues know what's up. no cap.

---

🌸 SYNOPSIS 🌸

void igb_setup_mrqc (struct igb_adapter *adapter);

that's it. that's the whole signature. it returns void, so don't go looking for a return value, she gives nothing back and honestly? mood. 💀

---

🦋 ARGUMENTS 🦋

• adapter — the board private structure 🫶 this is the per-board info blob that gets passed in, and it's the only thing this function wants.
