STRUCT IWL_SCD_TXQ_CFG_CMD(9)

💅 struct iwl_scd_txq_cfg_cmd — a Kernel API Manual moment

okay so bestie, welcome to the struct iwl_scd_txq_cfg_cmd page — this is a Kernel API Manual entry and honestly it's giving "small struct, big responsibilities" energy ✨

---

✨ NAME ✨

struct iwl_scd_txq_cfg_cmd — the New txq hw scheduler config command. that's it, that's the whole vibe. it configures a hardware scheduler queue, and we're gonna learn it together 🫶

---

🌸 SYNOPSIS 🌸

here's the whole little guy, look at it:

struct iwl_scd_txq_cfg_cmd {
    u8 token;
    u8 sta_id;
    u8 tid;
    u8 scd_queue;
    u8 action;
    u8 aggregate;
    u8 tx_fifo;
    u8 window;
    __le16 ssn;
    __le16 reserved;
 };

like, so many u8s. it's basically a u8 girl summer 💀 (and then two __le16s show up at the end to keep it interesting)

🎀 Members 🎀

• token — unused. literally does nothing. it's just there. main character energy of a struct field that never gets called 🧚
• sta_id — the station id 💖
• tid — the TID ✨
• scd_queue — the scheduler queue to confiug. yes, "confiug". that's how it's spelled in the source and we are not fixing it, we respect the typo 🙈 (for the record, it means: the scheduler queue to configure)
• action — the mood ring of this struct: 1 = queue enable, 0 = queue disable, 2 = change txq's tid owner. the value is one of the enum iwl_scd_cfg_actions options 👑
• aggregate — 1 = aggregated queue, 0 = otherwise. no in-between, we love a binary icon ⭐
• tx_fifo — an enum iwl_mvm_tx_fifo, okurrr 🦋
• window — the BA window size 🌈
• ssn — the SSN for the BA agreement 💜
• reserved — reserved. it's reserved, bestie, don't touch it 💅

okay that's the page!! and for the sign-off, this absolute gem comes from ./drivers/net/wireless/intel/i... (that's the source path, truncated by the manpage abuser itself, not by me 😭) and it's dated October 2026 — so mark your calendars, bestie, and go forth and configure those scheduler queues. slay 🎀✨🦋
