ice_sched_set_q_bw_lmt(9)

✨ NAME ✨

So like, ice_sched_set_q_bw_lmt is literally the function that sets queue BW limit — that's bandwidth limit for the queue scheduling node. Periodt. 💅

---

✨ SYNOPSIS ✨

int ice_sched_set_q_bw_lmt (struct ice_port_info *pi , u16 vsi_handle ,
u8 tc , u16 q_handle , enum ice_rl_type rl_type , u32 bw );

---

✨ ARGUMENTS ✨

Okay bestie, here's the whole cast of characters you're passing in:

• pi — the port information structure, aka the main character data block. 🫶
• vsi_handle — the sw VSI handle, it's a u16 and it's giving "which virtual station interface are we talking about" energy.
• tc — the traffic class, a u8 because sometimes you just gotta keep it cute and small. 🌸
• q_handle — the software queue handle, u16 — this is the queue's little name tag.
• rl_type — the rate limit type, and it's an enum ice_rl_type. It can be min, max, or shared. Choose your fighter. ⭐
• bw — the bandwidth, in Kbps, as a u32. That's the actual number, no cap.

---

✨ DESCRIPTION ✨

This function sets the BW limit of a queue scheduling node. That's it. That's the whole vibe. 🎯

Like, it literally just sets the bandwidth limit for a queue scheduling node. It's focused, it's iconic, it knows what it's about. 🔥
