netif_subqueue_stopped(9)

💅 NAME 💅

netif_subqueue_stopped — the function whose entire personality is testing the status of a subqueue. That's it. That's the whole gig. And honestly? periodt. ✨

This little icon lives in the Kernel API Manual, so bestie, you know it's real kernel business 🫶

---

🎀 SYNOPSIS 🎀

bool netif_subqueue_stopped (const struct net_device *dev , struct
       sk_buff *skb );

Not me giving you a bool return type right up front — yes, it hands you back a true-or-false situation, no cap 💅

---

🦋 ARGUMENTS 🦋

• dev — the network device. like, the actual device you're asking about, const struct net_device * and everything ⭐
• skb — the sub queue buffer pointer, a struct sk_buff * — this is the one that points at the sub queue you care about 🍓

---

🔥 DESCRIPTION 🔥

Okay so here's the vibe: this one checks the individual transmit queue of a device with multiple transmit queues. That's the entire description. Multiple tx queues? It's looking at the individual one, not the whole fleet. iconic behaviour honestly 👑

Lowkey the whole point: it's the *sub*queue version of the question, for devices that have more than one transmit queue to keep track of. Don't @ me, that's literally what the page says 💀
