STRUCT IWL_RX_PHY_INFO(9)

💖 struct iwl_rx_phy_info(9) 💖

okay bestie, sit down, grab a boba, because we're about to get deep into the iwlwifi kernel API manual — this is a struct page from the Kernel API Manual, so it's giving very much "reference doc but make it fashion" 🌸

---

✨ NAME ✨

struct iwl_rx_phy_info — the phy info struct, aka the one that shows up with REPLY_RX_PHY_CMD = 0xc0 🎀

lowkey the whole vibe is: it's the PHY info payload, and yes it is iconic for that 🫶

---

🦋 SYNOPSIS 🦋

struct iwl_rx_phy_info {
    u8 non_cfg_phy_cnt;
    u8 cfg_phy_cnt;
    u8 stat_id;
    u8 reserved1;
    __le32 system_timestamp;
    __le64 timestamp;
    __le32 beacon_time_stamp;
    __le16 phy_flags;
    __le16 channel;
    __le32 non_cfg_phy[IWL_RX_INFO_PHY_CNT];
    __le32 rate_n_flags;
    __le32 byte_count;
    u8 mac_active_msk;
    u8 mac_context_info;
    __le16 frame_time;
};

like, look at her. every field accounted for, no notes 💅

🌈 MEMBERS 🌈

• non_cfg_phy_cnt — the byte count for the non-configurable DSP phy data. she's counting bytes and she's slaying ✨
• cfg_phy_cnt — byte count for the configurable DSP phy data. same energy, different bucket 🍓
• stat_id — the ID of the configurable DSP phy data set. it's her little name tag 🎀
• reserved1 — reserved. not for us, bestie, we don't touch 🙈
• system_timestamp — GP2 at on air rise. yes, exactly what it sounds like 😌
• timestamp — TSF at on air rise. the timeline queen herself 👑
• beacon_time_stamp — beacon at on-air rise. it's giving punctual ⭐
• phy_flags — general phy flags: band, modulation, ... (the ... is canon, we don't elaborate, that's not our business 🤫)
• channel — the channel number. simple, clean, effective 💜
• non_cfg_phy — there's various implementations of non_cfg_phy, and this field is for all of them. versatility, we love to see it 🦋
• rate_n_flags — the RATE_MCS_* situation 🌸
• byte_count — the frame's byte-count, keeping receipts 🧾
• mac_active_msk — which MACs were active when the frame got received. a whole attendance sheet fr fr 💀
• mac_context_info — extra info about the context the frame was received in, as defined in enum iwl_mac_context_info. the backstory, the lore ✨
• frame_time — the frame's time on the air, based on byte count and frame rate calculation. math girlies rise 🔥

💫 DESCRIPTION 💫

so here's the tea: before each Rx, the device sends this data. that's just the rules. and it contains the PHY information about the reception of the packet 😭 like it literally arrives with the vibes pre-loaded, no cap.

ngl, this page is straight-up kernel documentation — read it carefully before you go poking at rx.h, okay? the struct fields are literal and the (9) tags mean business 💅
