STRUCT IWL_MAC_CONFIG_CMD_V3(9)

💖 struct iwl_mac_config_cmd_v3 — from the Kernel API Manual ✨

okay bestie so this is a page straight out of the Kernel API Manual, and it's all about struct iwl_mac_config_cmd_v3. gorgeous name, iconic struct, let's get into it 🫶

---

✨ NAME ✨

struct iwl_mac_config_cmd_v3 — the command structure you use to configure MAC contexts in the MLD API, for versions 2 and 3. and the subcommand id for it? MAC_CONTEXT_CONFIG_CMD = 0x8 🎀

---

🌸 SYNOPSIS 🌸

struct iwl_mac_config_cmd_v3 {
    __le32 id_and_color;
    __le32 action;
    __le32 mac_type;
    u8 local_mld_addr[6];
    __le16 reserved_for_local_mld_addr;
    __le32 filter_flags;
    union {
      struct iwl_mac_wifi_gen_support_v2 wifi_gen_v2;
      struct iwl_mac_wifi_gen_support wifi_gen;
    };
    __le32 nic_not_ack_enabled;
    union {
      struct iwl_mac_client_data client;
      struct iwl_mac_p2p_dev_data p2p_dev;
    };
 };

look at that layout. the alignment? ate. no notes 💅

🦋 Members 🦋

• id_and_color — the ID and the color of the MAC. yes, both, in one field, we love a two-for-one 💖
• action — the action you're performing. check enum iwl_ctxt_action for your options.
• mac_type — one of enum iwl_mac_types.
• local_mld_addr — the mld address. it's a u8 local_mld_addr[6], so, y'know, six of them 🌸
• reserved_for_local_mld_addr — reserved. that's it. that's the whole vibe. don't touch it 🙈
• filter_flags — a combination of enum iwl_mac_config_filter_flags. mix and match bestie ✨
• {unnamed_union} — anonymous. she has no name and she doesn't need one 👑
  • wifi_gen_v2 — he/eht parameters, as in cmd version 2.
  • wifi_gen — he/eht/uhr parameters, as in cmd version 3. (yes version 3 got the extra uhr, main character energy honestly ⭐)
• nic_not_ack_enabled — this one marks that the NIC doesn't support receiving ACK-enabled AGG, and by that we mean both BACK and non-BACK frames in a single AGG. if the NIC is not ACK_ENABLED it may use the EOF-bit in the first non-0 len delim to figure out whether it's looking at AGG or a single 🔥
• {unnamed_union} — anonymous again. twin anonymous unions, we stan a lowkey matching set 💜
  • client — the client mac data.
  • p2p_dev — the mac data for p2p device.

fr fr do not repurpose reserved_for_local_mld_addr for your little side quest. it says reserved and it means reserved 😭

and that's the page!! 🌈 the footer's giving ./drivers/net/wireless/intel/i... with October 2026 stamped on it (and the title running down the side as struct iwl_m...onfig_cmd_v3(9) because even manpage headers get truncated sometimes 😭). anyway bestie you're now officially unbothered, informed, and fluent in MLD MAC config. slay 💅💖
