STRUCT IWL_STA_CFG_CMD_V2(9)

💖 NAME 💖

struct iwl_sta_cfg_cmd_v2 — the cmd structure to add a peer sta to the uCode's station table (STA_CONFIG_CMD = 0xA). Bestie, that's the whole name vibe: Kernel API Manual, section 9, and it's giving station-table realness. ✨

🫶 Members 🫶

okay bestie, here's the field-by-field tour — every single member, no skips, no "oops I forgot one" energy. 💅

• sta_id — index of station in uCode's station table.
• link_id — the id of the link that is used to communicate with this sta.
• peer_mld_address — the peers mld address.
• reserved_for_peer_mld_address — reserved.
• peer_link_address — the address of the link that is used to communicate with this sta.
• reserved_for_peer_link_address — reserved.
• station_type — type of this station. See enum iwl_fw_sta_type.
• assoc_id — for GO only.
• beamform_flags — beam forming controls.
• mfp — indicates whether the STA uses management frame protection or not.
• mimo — indicates whether the sta uses mimo or not.
• mimo_protection — indicates whether the sta uses mimo protection or not.
• ack_enabled — indicates that the AP supports receiving ACK- enabled AGG, i.e. both BACK and non-BACK frames in a single AGG.
• trig_rnd_alloc — indicates that trigger based random allocation is enabled according to UORA element existence.
• tx_ampdu_spacing — minimum A-MPDU spacing: 4 - 2us density, 5 - 4us density, 6 - 8us density, 7 - 16us density.
• tx_ampdu_max_size — maximum A-MPDU length: 0 - 8K, 1 - 16K, 2 - 32K, 3 - 64K, 4 - 128K, 5 - 256K, 6 - 512K, 7 - 1024K.
• sp_length — the size of the SP in actual number of frames.
• uapsd_acs — 4 LS bits are trigger enabled ACs, 4 MS bits are the deliver enabled ACs.
• pkt_ext — optional, exists according to PPE-present bit in the HE/EHT-PHY capa.
• htc_flags — which features are supported in HTC.
• use_ldpc_x2_cw — Indicates whether to use LDPC with double CW.
• use_icf — Indicates whether to use ICF instead of RTS.
• dps_pad_time — DPS (Dynamic Power Save) padding delay resolution to ensure proper timing alignment.
• dps_trans_delay — DPS minimal time that takes the peer to return to low power.
• mic_prep_pad_delay — MIC prep time padding.
• mic_compute_pad_delay — MIC compute time padding.
• reserved — Reserved for alignment.
