STRUCT IWL_MCC_UPDATE_CMD(9)

💅 struct iwl_mcc_update_cmd — the group chat version

okay bestie, so we're deep in the kernel API manual for struct iwl_mcc_update_cmd and honestly? it's giving "please update my geographic regulatory profile" energy and I'm obsessed. 🗺️✨

---

✨ NAME ✨

struct iwl_mcc_update_cmd — this little cutie asks the device to update its geographic regulatory profile according to the given MCC (Mobile Country Code). 💖

so like, the MCC is a two-letter code, ascii upper case [A-Z], or '00' for the world domain. and yes, 'ZZ' is a whole vibe too: that MCC switches things over to the NVM default profile — and in that case the MCC you'll see in the cmd response is the relevant MCC in the NVM. no cap. 👑

---

🌸 SYNOPSIS 🌸

struct iwl_mcc_update_cmd {
    __le16 mcc;
    u8 source_id;
    u8 reserved;
    __le32 key;
    u8 reserved2[20];
 };

look at her. iconic. 🎀

🦋 Members 🦋

• mcc — the given mobile country code, literally the whole point of this struct fr fr
• source_id — the source from where we got the MCC, see iwl_mcc_source 💫
• reserved — reserved for alignment (bestie just needs her space to line up, respect it)
• key — integrity key for MCC API OEM testing 🔑
• reserved2 — reserved (yes, again — it's reserved, we don't ask questions) 🙈

quick vibe check: the MCC must be two letters, ascii upper case [A-Z], or '00' for world domain — and 'ZZ' means "switch to NVM default profile", with the response then carrying the relevant MCC in the NVM. that part is not optional bestie, that's just how she is. 💅

and that's the page!! 🫶 this one came straight out of ./drivers/net/wireless/intel/i... — yes the path got cut off mid-word, she's mysterious like that 💀 — dated October 2026, and it's all for struct iwl_mcc_update_cmd(9). slay, go read your regulatory profiles, mwah 🧚💜
