netif_queue_stopped(9)

💅 netif_queue_stopped(9) — Kernel API Manual ✨

okay so bestie, welcome to the glow-up of netif_queue_stopped(9), fresh out of the Kernel API Manual. this one's short, sweet, and honestly kind of a vibe check for your NIC 🫶

---

🌸 NAME 🌸

netif_queue_stopped — test if transmit queue is flowblocked 💀

like, is the queue blocked or is it fine? that's the whole assignment. no cap.

---

🦋 SYNOPSIS 🦋

bool netif_queue_stopped (const struct net_device *dev );

she takes one arg, she returns a bool, she does not elaborate 💅

---

🎀 ARGUMENTS 🎀

• dev — network device 🌈 (the icon herself, the net_device we're checking on)

---

⭐ DESCRIPTION ⭐

Test if transmit queue on device is currently unable to send. 🚦

that's it, that's the plot. you hand her a dev, she tells you whether that device's transmit queue is currently unable to send. lowkey the most straightforward function in the whole kernel and honestly? respect. 🔥
