💅 dev_change_tx_queue_len — like, the whole vibe of a kernel API page, but make it make sense

okay so bestie, welcome to the Kernel API Manual 🎀 — this is the page for dev_change_tx_queue_len, and yes it does exactly what it says on the tin, no cap.

✨ NAME ✨

dev_change_tx_queue_len — changes the TX queue length of a netdevice 💖

---

🌸 SYNOPSIS 🌸

int dev_change_tx_queue_len (struct net_device *dev , unsigned long
new_len );

that's it. two arguments. she's simple, she's iconic, she's literally a one-liner 🦋

---

👑 ARGUMENTS 👑

• dev — the device 💻 (your netdevice, the main character of this whole operation)
• new_len — the new tx queue length ⭐ (the fresh number you're handing over)
