STRUCT IWL_TX_CMD_V9(9)

💅 struct iwl_tx_cmd_v9(9)

okay so bestie, buckle up — this is a page straight out of the Kernel API Manual ✨ and it's all about the TX command struct that gets yeeted to the firmware on 22000 devices. the header said struct iwl_tx_cmd_v9(9) and honestly? iconic. let's get into it 🎀

🌸 NAME 🌸

struct iwl_tx_cmd_v9 — the TX command struct you send to the FW for 22000 devices (and like, yes, TX_CMD = 0x1c 💫)

✨ SYNOPSIS ✨

struct iwl_tx_cmd_v9 {
    __le16 len;
    __le16 offload_assist;
    __le32 flags;
    struct iwl_dram_sec_info dram_info;
    __le32 rate_n_flags;
    struct ieee80211_hdr hdr[];
 };

look at her. the flexible array member at the end? main character energy fr fr 👑

🦋 Members 🦋

• len — the length in bytes of the payload, and yes there's more detail on that below, so don't @ me 💖
• offload_assist — the TX offload configuration, aka the vibe check for how much work we're handing off 🫶
• flags — a combo of enum iwl_tx_cmd_flags, pick your faves 🌈
• dram_info — the FW's internal DRAM storage, very much the secret little pocket dimension 🙈
• rate_n_flags — the rate for all the Tx attempts, but ONLY if TX_CMD_FLG_STA_RATE_MSK is cleared, and it's a combination of RATE_MCS_* — note the all in italics, she's serious about that one ⭐
• hdr — the 802.11 header, the whole point of the party 🎉
