ice_sched_set_node_bw(9)

💖 ice_sched_set_node_bw(9) 💖

okay so bestie, welcome to the Kernel API Manual entry for ice_sched_set_node_bw. we're setting node bandwidth, and yes, it's giving main-character scheduler energy. 🫶

---

🌸 NAME 🌸

ice_sched_set_node_bw — set node's bandwidth. periodt. 💅

---

✨ SYNOPSIS ✨

int ice_sched_set_node_bw (struct ice_port_info *pi , struct
       ice_sched_node *node , enum ice_rl_type rl_type , u32 bw , u8 layer_num
       );

---

🎀 ARGUMENTS 🎀

• pi — the port information structure. it's literally right there in the name, bestie.
• node — the tree node. yes, that one. 🌳
• rl_type — rate limit type: min, max, or shared. choose your fighter. ⚔️
• bw — bandwidth in Kbps - Kilo bits per sec. keep it exact, no vibes-based units. 🔥
• layer_num — layer number. the layer. the number. iconic. ✨

---

🦋 DESCRIPTION 🦋

okay so this function adds a new profile corresponding to the requested BW, configures the node's RL profile ID of type CIR, EIR, or SRL, and removes the old profile ID from the local database. that's the whole serve. 💅

the caller needs to hold the scheduler lock. no cap, this is important — don't skip the lock. 🔒
