STRUCT IWL_LQ_CMD(9)

💅 struct iwl_lq_cmd — link quality command 💅

okay bestie, this is from the Kernel API Manual (the struct iwl_lq_cmd(9) page, to be exact), and it's literally the link quality command. no cap, it's giving "here's the whole struct, every field, don't skip a single one" energy. let's get into it 🫶

✨ SYNOPSIS ✨

like, here's the whole thing, character for character, because we do NOT paraphrase code in this house 💖

struct iwl_lq_cmd {
    u8 sta_id;
    u8 reduced_tpc;
    __le16 control;
    u8 flags;
    u8 mimo_delim;
    u8 single_stream_ant_msk;
    u8 dual_stream_ant_msk;
    u8 initial_rate_index[AC_NUM];
    __le16 agg_time_limit;
    u8 agg_disable_start_th;
    u8 agg_frame_cnt_limit;
    __le32 reserved2;
    __le32 rs_table[LQ_MAX_RETRY_NUM];
    __le32 ss_params;
 };

🎀 Members 🎀

okay so, field by field, no skipping, that's the rule 👑

• sta_id — the station you're updating. that's it, that's the whole vibe ✨
• reduced_tpc — reduced transmit power control value 🌸
• control — not used. iconic honestly, just vibing there 💀
• flags — a combination of LQ_FLAG_* 🦋
• mimo_delim — the first SISO index in rs_table, which separates MIMO and SISO rates. she's the divider, the boundary, the main character of rate separation 💅
• single_stream_ant_msk — best antenna for SISO (can be dual in CDD). Should be ANT_[ABC] ⭐
• dual_stream_ant_msk — best antennas for MIMO, combination of ANT_[ABC] 🔥
• initial_rate_index — first index from rs_table per AC category 🌈
• agg_time_limit — aggregation max time threshold in usec/100, meaning value of 100 is one usec. Range is 100 to 8000. bestie read that twice, the units are sneaky 🙈
• agg_disable_start_th — try-count threshold for starting aggregation. If a frame has higher try-count, it should not be selected for starting an aggregation sequence. like, if you already tried too hard, you're not starting the group project, sorry 💀
• agg_frame_cnt_limit — max frame count in an aggregation. 0: no limit. 1: no aggregation (one frame per aggregation). 2 - 0x3f: maximal number of frames (up to 3f == 63) 🍓
• reserved2 — reserved. respectfully reserved. she's not participating today 🎀
• rs_table — array of rates for each TX try, each is rate_n_flags, meaning it is a combination of RATE_MCS_* and IWL_RATE_*_PLCP 💜
• ss_params — single stream features. declare whether STBC or BFER are allowed. it's giving "fill out the permission slip" energy 🧚

ngl that's a long list but every single one is on here for a reason, so don't come for me 😭

and that's the page!! this one came from ./drivers/net/wireless/intel/i..., dated October 2026 — ty for coming to my ted talk, ily, go update your link quality commands responsibly 💖✨👑
