STRUCT IWL_STA_CFG_CMD_V1(9)

💅 struct iwl_sta_cfg_cmd_v1(9) 💅

okay bestie, so this is a page from the Kernel API Manual, and honestly? it's giving "under the hood of your wifi" realness. we're looking at struct iwl_sta_cfg_cmd_v1 — no cap, this is the cmd structure you use to add a peer sta to the uCode's station table, and its little ID badge says STA_CONFIG_CMD = 0xA. iconic. 🎀

✨ SYNOPSIS ✨

struct iwl_sta_cfg_cmd_v1 {
    __le32 sta_id;
    __le32 link_id;
    u8 peer_mld_address[ETH_ALEN];
    __le16 reserved_for_peer_mld_address;
    u8 peer_link_address[ETH_ALEN];
    __le16 reserved_for_peer_link_address;
    __le32 station_type;
    __le32 assoc_id;
    __le32 beamform_flags;
    __le32 mfp;
    __le32 mimo;
    __le32 mimo_protection;
    __le32 ack_enabled;
    __le32 trig_rnd_alloc;
    __le32 tx_ampdu_spacing;
    __le32 tx_ampdu_max_size;
    __le32 sp_length;
    __le32 uapsd_acs;
    struct iwl_he_pkt_ext_v2 pkt_ext;
    __le32 htc_flags;
 };

like, look at all those fields. she's thorough. 🦋

👯 MEMBERS 👯

• sta_id — the index of the station in the uCode's station table. her little seat number, basically. 💺
• link_id — the id of the link that is used to communicate with this sta. which link? that link. 🔗
• peer_mld_address — the peer's mld address. straightforward, we love her.
• reserved_for_peer_mld_address — reserved. that's it. that's the whole vibe. don't touch. 🙈
• peer_link_address — the address of the link that is used to communicate with this sta. yes it's a second address, she contains multitudes. 🦋
• reserved_for_peer_link_address — reserved. again. hands off, bestie. 💀
• station_type — the type of this station. peek at enum iwl_fw_sta_type if you wanna know more, iykyk. 👑
• assoc_id — for GO only. that's the whole note. short and mysterious. ✨
• beamform_flags — beam forming controls. beep boop, shape that signal. 📡
• mfp — tells you whether the STA uses management frame protection or not. yes/no energy. 🔥
• mimo — tells you whether the sta uses mimo or not. again with the yes/no. 📶
• mimo_protection — tells you whether the sta uses mimo protection or not. third time's the charm.
• ack_enabled — indicates that the AP supports receiving ACK-enabled AGG, i.e. both BACK and non-BACK frames in a single AGG. lowkey a mouthful but she said what she said. 💅
• trig_rnd_alloc — indicates that trigger based random allocation is enabled according to UORA element existence. fancy. 🌸
• tx_ampdu_spacing — minimum A-MPDU spacing, and here's the cheat sheet: 4 - 2us density, 5 - 4us density, 6 - 8us density, 7 - 16us density. memorize it or don't, i'm not your mom. 🎀
• tx_ampdu_max_size — maximum A-MPDU length, another cheat sheet: 0 - 8K, 1 - 16K, 2 - 32K, 3 - 64K, 4 - 128K, 5 - 256K, 6 - 512K, 7 - 1024K. the way it just keeps going up 😭
• sp_length — the size of the SP in actual number of frames. actual frames. not vibes. frames. 🧚
• uapsd_acs — the 4 LS bits are trigger enabled ACs, and the 4 MS bits are the deliver enabled ACs. bit math, but make it cute. ⭐
• pkt_ext — optional, exists according to the PPE-present bit in the HE/EHT-PHY capa. so like, she shows up only if she's invited. 🫶
• htc_flags — which features are supported in HTC. the ✨feature flags✨ of it all.

that's the whole page bestie, go forth and configure your stations 💖✨🎀
