STRUCT IWL_TLC_CONFIG_CMD_V4(9)

💖 struct iwl_tlc_config_cmd_v4(9) — TLC configuration 💖

okay bestie so you're in the Kernel API Manual and this page is literally the blueprint for struct iwl_tlc_config_cmd_v4 — aka the TLC configuration struct, version 4, no cap ✨. It's giving "rate control but make it structured," and we're gonna go through every single field together because that's what friends do 🫶

✨ SYNOPSIS ✨

struct iwl_tlc_config_cmd_v4 {
    u8 sta_id;
    u8 reserved1[3];
    u8 max_ch_width;
    u8 mode;
    u8 chains;
    u8 sgi_ch_width_supp;
    __le16 flags;
    __le16 non_ht_rates;
    __le16 ht_rates[IWL_TLC_NSS_MAX][IWL_TLC_MCS_PER_BW_NUM_V4];
    __le16 max_mpdu_len;
    __le16 max_tx_op;
 };

that's the whole cast of characters, and yes we're meeting all of them 💅

🎀 Members 🎀

• sta_id — the station id. which station are we even talking about, that's this one 💫
• reserved1 — reserved. like, do not touch, it's not for you, it's saving a seat at the lunch table 🪑
• max_ch_width — the max supported channel width, pulled from enum iwl_tlc_mng_cfg_cw. how wide can we go, that's the question 🌈
• mode — enum iwl_tlc_mng_cfg_mode. the vibes/mode selector 🦋
• chains — a bitmask of enum iwl_tlc_mng_cfg_chains. bitmask of chains, periodt 🔗
• sgi_ch_width_supp — bitmap of SGI support per channel width — use BIT(enum iwl_tlc_mng_cfg_cw). one bit per width, so organized 💅
• flags — a bitmask of enum iwl_tlc_mng_cfg_flags. yes, more bits, we love bits ⭐
• non_ht_rates — bitmap of supported legacy rates. the non-HT ones, the classics, the old money 👑
• ht_rates — bitmap of enum iwl_tlc_mng_ht_rates, per <nss, channel-width> pair. and the mapping is lowkey specific: (0 - 80mhz width and below, 1 - 160mhz, 2 - 320mhz). write that down bestie 🍓
• max_mpdu_len — max MPDU length, in bytes. bytes!! 📏
• max_tx_op — max TXOP in uSecs for all AC (BK, BE, VO, VI), set zero for no limit. zero = unlimited, going feral with it 🔥

ok that's the whole page, you ate that 💅 go read the v3 struct too, it's giving prequel energy

and that's a wrap bestie 🧚💜 this little love letter came from ./drivers/net/wireless/intel/i... and it's stamped October 2026 — struct iwl_t...onfig_cmd_v4(9), signing off 🎀
