💅 ice_sched_set_node_bw_lmt_per_tc — set node BW limit per TC ✨

Okay so bestie, real talk: this page lives in the Kernel API Manual, and it's about telling an Intel ice scheduling node how much bandwidth it's allowed to have — per traffic class. Very demure, very mindful, very network-QoS. 🎀

🌸 NAME 🌸

ice_sched_set_node_bw_lmt_per_tc — set node BW limit per TC

---

🦋 SYNOPSIS 🦋

int ice_sched_set_node_bw_lmt_per_tc (struct ice_port_info *pi , u32 id
, enum ice_agg_type agg_type , u8 tc , enum ice_rl_type rl_type , u32 bw
);

---

🍓 ARGUMENTS 🍓

• pi — the port information structure, aka the whole vibe of the port you're messing with 💖
• id — the ID. It's either a software VSI handle or an AGG ID, depending on what you're doing ✨
• agg_type — the aggregator type (a VSI node type or an AGG type node, pick your fighter) 🦋
• tc — traffic class. yes we're doing per-TC things, stay with me 👑
• rl_type — min or max. as in, the rate-limit type. min. or max. that's the whole menu 💅
• bw — bandwidth in Kbps, not bytes, not Mbps, Kbps, write it down 📝

---

🌈 DESCRIPTION 🌈

So what this function does is it sets the BW limit of a VSI or an Aggregator scheduling node 🔥 — and it does it based on the TC information plus the bw you passed in as an argument. Like, you hand it a bandwidth, it goes "say less" and applies the limit to that node for that traffic class. No cap. 🫶

💀 friendly reminder that this is a bandwidth limit, so pick your rl_type and bw values like you mean it, bestie. The page doesn't promise anything about what happens if you don't — it just says what the function does. 🙈

Okay that's the whole page, mwah 💋 — brought to you by the source path ./drivers/net/ethernet/intel/ice and dated October 2026, still serving looks in ice_sched_se...w_lmt_per_tc(9) format. Go set those limits, queen 👑✨
