STRUCT IWL_MAC_CONFIG_CMD(9)

🌸 NAME 🌸

okay bestie, so this is literally struct iwl_mac_config_cmd — the command structure to configure MAC contexts in the MLD API for versions 4, and you know the command ID is MAC_CONTEXT_CONFIG_CMD = 0x8 💅. it's giving main character energy in the kernel API manual, fr fr.

✨ SYNOPSIS ✨

struct iwl_mac_config_cmd {
    __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;
      struct iwl_mac_nan_data nan;
    };
 };

like, this is the whole vibe of the struct — don't touch it, it's iconic ✨

💅 Members 💅

• id_and_color — the ID and color of the MAC, no cap 🎀
• action — the action to perform, check enum iwl_ctxt_action for the deets 🔥
• mac_type — one of enum iwl_mac_types, pick your fighter 💅
• local_mld_addr — the mld address, periodt 🦋
• reserved_for_local_mld_addr — reserved, don't touch, it's giving placeholder vibes 🙈
• filter_flags — a combination of enum iwl_mac_config_filter_flags, mix and match bestie 🌸
• {unnamed_union} — anonymous, lowkey mysterious 💀
• wifi_gen_v2 — he/eht parameters as in cmd version 2, vintage but valid ✨
• wifi_gen — he/eht/uhr parameters as in cmd version 3, the upgraded vibe 🚀
• nic_not_ack_enabled — marks that the NIC doesn't support receiving ACK-enabled AGG (that's both BACK and non-BACK frames in a single AGG, iykyk). if the NIC is not ACK_ENABLED it may use the EOF-bit in the first non-0 len delim to determine if it's AGG or single. fr fr, that's important 💅
• {unnamed_union} — anonymous, again, still mysterious 🫶
• client — client mac data, the main character energy 👑
• p2p_dev — mac data for p2p device, peer-to-peer slay 🌈
• nan — NAN specific data (NAN data interface addresses), niche but iconic ⭐
