ice_devlink...d_layers_set(9)

💅 ice_devlink...d_layers_set(9) — like, the whole vibe ✨

okay bestie, so this is a page from the Kernel API Manual, section 9, and the header up top literally reads ice_devlink...d_layers_set(9) 🎀 — yes it's truncated, that's just how it printed, we move. It's all about ice_devlink_tx_sched_layers_set, and ngl it's a short one but it ate. Let's go 🫶

---

🌸 NAME 🌸

ice_devlink_tx_sched_layers_set — literally sets the tx_scheduling_layers parameter. That's the whole job. Main character energy, one task, no notes 💅

---

✨ SYNOPSIS ✨

int ice_devlink_tx_sched_layers_set (struct devlink *devlink , u32 id ,
       struct devlink_param_gset_ctx *ctx , struct netlink_ext_ack *extack );

so it returns an int, takes four things, and yes you have to keep them in that exact order, no cap 🔥

---

🦋 ARGUMENTS 🦋

• devlink — pointer to the devlink instance, like your lil handle to the thing 🎀
• id — the parameter ID to set, iykyk which one you're poking at
• ctx — context to get the parameter value; that's where the value situation lives 💖
• extack — the netlink extended ACK structure, for when the kernel needs to talk back ✨

---

🌈 RETURN 🌈

• zero on success — slay 👑
• negative value on failure — not slay, but that's the contract 😭

fr fr, zero means good, negative means something went sideways. Don't invert that, bestie 💀
