gether_set_qmult(9)

💅 gether_set_qmult — kernel API manual, section 9, bestie 💅

Ok so real talk, this one lives in the Kernel API Manual (section 9), and it's short but it's mighty. Let's get into it ✨

---

🌸 NAME 🌸

gether_set_qmult — bestie. it literally initializes an ethernet-over-usb link with a multiplier. that's the whole vibe. 🦋

---

✨ SYNOPSIS ✨

void gether_set_qmult (struct net_device *net , unsigned qmult );

not me giving you the exact signature character-for-character because we do NOT play about prototypes 💀

---

🎀 ARGUMENTS 🎀

• net — this is the device that represents this link. like, the actual net_device, the main character here 👑
• qmult — the queue multiplier. it's an unsigned, it's a multiplier, it multiplies queues. iykyk 💜

---

🔥 DESCRIPTION 🔥

So what this does: it sets the queue length multiplier of this ethernet-over-usb link. periodt. 🫶

And the golden rule of it — for higher speeds use longer queues. that's it, that's the tea. faster link = longer queue, no cap. ✨
