cxgb4_sched_class_bind(9)

💅 cxgb4_sched_class_bind(9) — the kernel API manual, but make it make sense

okay bestie, welcome to section 9 of the Kernel API Manual, where we talk about cxgb4_sched_class_bind — the little Chelsio cxgb4 function that does exactly one job and honestly? slays at it. let's get into it 🎀

---

✨ NAME ✨

cxgb4_sched_class_bind — bind an entity to a scheduling class. that's it. that's the whole vibe 🦋

---

🌸 SYNOPSIS 🌸

int cxgb4_sched_class_bind (struct net_device *dev , void *arg , enum
       sched_bind_type type );

like, three things go in, an int comes out. iconic behavior fr fr ✨

---

💖 ARGUMENTS 💖

• dev — a net_device pointer. your netdev. your main character. 👑
• arg — the entity's opaque data. it's opaque, bestie, don't try to peek under the hood 🙈
• type — the entity type, and the type is Queue. that's the one on the menu 💅

---

🦋 DESCRIPTION 🦋

so what does it actually do? it binds an entity (a queue, iykyk) to a scheduling class. simple. clean. no cap.

and here's the plot twist 👀 — if that entity is already bound to another class, it gets unbound from the other class first, and then bound to the class specified in arg. so it's not a "two-timing two classes" situation, it's a "dump the old class and commit to the new one" situation. very main character energy, honestly 💀✨

and that's the whole page, bestie 🎀 this came straight out of the Linux kernel source tree at ./drivers/net/ethernet/chelsio/..., dated October 2026, and it's the cxgb4_sched_class_bind(9) page from the Kernel API Manual. go forth and bind responsibly 💜🌸
