STRUCT IWL_DHC_TLC_CMD(9)

💅 struct iwl_dhc_tlc_cmd(9) 💅

okay so bestie, we're deep in the Kernel API Manual today and honestly? it's giving niche-but-iconic. this is the struct iwl_dhc_tlc_cmd page, aka the fixed debug config — yes that's the actual NAME, and yes it slays in a very specific "i work on wireless firmware" way 🦋

---

✨ SYNOPSIS ✨

like, here's the whole vibe, literally character for character, don't touch it:

struct iwl_dhc_tlc_cmd {
    u8 sta_id;
    u8 reserved1[3];
    __le32 type;
    __le32 data[MAX_DATA_IN_DHC_TLC_CMD];
 };

no cap, that's the entire struct. she's compact, she's efficient, she has a mysterious reserved1 array that's just there living her life 🎀

🌸 MEMBERS 🌸

okay now the fun part, the fields, the main characters of this whole thing:

• sta_id — so this one's a little bit of a multitasker 👑 bit 0 is the enable/disable situation, and bits 1 through 7 are holding the station id. one byte, two jobs, we love a hustler.
• reserved1 — reserved 🙈 that's it. that's the description. she's reserved, she's mysterious, don't ask her questions.
• type — the type id, and it comes from enum iwl_tlc_debug_types. iykyk 🔥
• data — literally just the data to send. the payload. the moment. data to send 💖 and it's sized MAX_DATA_IN_DHC_TLC_CMD, which, iconic name honestly.

🔍 SEE ALSO 🔍

okay so if you wanna go down the rabbit hole (and you do, bestie), here's the full squad. not me listing every single one, but also yes, every single one, because we don't skip ✨

first up, the kernel file ./drivers/net/wireless/intel/iwlwifi/fw/api/rs.h — that's the address, the location, the home base 🏠

and then the whole friend group:

• enum iwl_tlc_mng_cfg_flags(9)
• enum iwl_tlc_mng_cfg_cw(9)
• enum iwl_tlc_mng_cfg_chains(9)
• enum iwl_tlc_mng_cfg_mode(9)
• enum iwl_tlc_mng_ht_rates(9)
• enum IWL_TLC_MCS_PER_BW(9)
• struct iwl_tlc_config_cmd_v3(9)
• struct iwl_tlc_config_cmd_v4(9)
• struct iwl_tlc_config_cmd(9)
• enum iwl_tlc_update_flags(9)
• struct iwl_tlc_update_notif(9)
• enum iwl_tlc_debug_types(9)
• struct iwl_lq_cmd(9)

like??? that's a whole friend group chat and this struct is in it 🫶 go read all of them, fr fr, they all cross-reference each other and it's lowkey adorable.

⚠️ real talk though: reserved1 is reserved. don't go writing your hopes and dreams in there, bestie. it's not for you. periodt. 💀

and that's the page!! 💜 big shoutout to the source over at ./drivers/net/wireless/intel/i... (yes it's truncated like that, that's how she arrived, we respect it) and the date stamp October 2026 — mark your calendars, this struct said see you then, mwah 💅✨🎀
