ice_sched_set_node_bw_lmt(9)

📦 version 7.3.1, in nixpkgs unstable

✨ ice_sched_set_node_bw_lmt(9) ✨

Okay so bestie, we're deep in the kernel API manual today — this one's a (9) page, so you already know it's some internal kernel-function lore 💅. It lives in the Kernel API Manual, and honestly? She's giving "small function, big responsibilities." Let's get into it 🎀

🌸 NAME 🌸

ice_sched_set_node_bw_lmt — literally just sets a node's BW limit, no cap 🫶

🦋 SYNOPSIS 🦋

int ice_sched_set_node_bw_lmt (struct ice_port_info *pi , struct
       ice_sched_node *node , enum ice_rl_type rl_type , u32 bw );

That's the whole signature, bestie — copy it exactly if you're typing it out, okay? 😭

💖 ARGUMENTS 💖

  • pi — the port information structure. Think of it as the home base 🏠.
  • node — a tree node. Yep, we're in tree territory now 🌳.
  • rl_type — the rate limit type: min, max, or shared. Pick your fighter ✨.
  • bw — bandwidth in Kbps — that's Kilo bits per sec, not kilobytes, don't get it twisted 🙈.

🔥 DESCRIPTION 🔥

So what does she actually do? She updates the node's BW limit parameters — specifically the BW RL profile ID of type CIR, EIR, or SRL. That's it, that's the job 👑

⚠️ But listen — the caller needs to hold the scheduler lock. No lock, no love. Do not skip this, fr fr 💀

🧚 Sign-off 🧚

That's the whole page, bestie — sourced from ./drivers/net/ethernet/intel/ice, dated October 2026, and yes, this is the ice_sched_set_node_bw_lmt(9) page you were looking for. Go forth, hold that scheduler lock, and set those BW limits like the icon you are ⭐💜
