STRUCT IWL_MVM_MGMT_MCAST_KEY_CMD_V1(9)

💖 struct iwl_mvm_mgmt_mcast_key_cmd_v1(9) 💖

okay so bestie, welcome to the kernel API manual for struct iwl_mvm_mgmt_mcast_key_cmd_v1 — that's the IGTK command (MGMT_MCAST_KEY = 0x1f), no cap, that's literally what it is 🎀

---

✨ NAME ✨

struct iwl_mvm_mgmt_mcast_key_cmd_v1 — the IGTK command (with MGMT_MCAST_KEY = 0x1f), serving looks in the kernel API manual 🦋

---

🌸 SYNOPSIS 🌸

here's the whole glow-up, laid out exactly like this:

struct iwl_mvm_mgmt_mcast_key_cmd_v1 {
    __le32 ctrl_flags;
    u8 igtk[16];
    u8 k1[16];
    u8 k2[16];
    __le32 key_id;
    __le32 sta_id;
    __le64 receive_seq_cnt;
};

like, that's the entire struct, and honestly? she ate 🔥

🧚 Members 🧚

time for the vibe check on every single field, because we do NOT skip ✋

• ctrl_flags — this one's an enum iwl_sta_key_flag, iykyk 👑
• igtk — the IGTK key material itself, the main character of this struct 💅
• k1 — unused. that's it. that's the whole job. lowkey unemployed but we still love her 🙈
• k2 — also unused. matching set with k1, iconic duo, zero responsibilities 💀
• key_id — the key ID 🎀
• sta_id — the station ID that support IGTK ⭐
• receive_seq_cnt — the initial RSC/PN needed for replay check, aka the security bestie keeping things in line 🔥

🫶 quick heads up bestie: the source path shows up truncated as ./drivers/net/wireless/intel/i... and the page footer is dated October 2026, with both the header and footer showing the short form struct iwl_m...t_key_cmd_v1(9) — that's just how it's printed, not a typo on my end, promise 🌈

and that's the whole page!! mwah 💋 — signed off from ./drivers/net/wireless/intel/i..., October 2026, struct iwl_m...t_key_cmd_v1(9). periodt 🎀✨
