STRUCT ATH_DFS_STATS(9)

🌸 struct ath_dfs_stats(9) 🌸

okay bestie, welcome to the Kernel API Manual entry for struct ath_dfs_stats — it's giving "DFS statistics per wiphy" and honestly it's a whole mood tracker for radar pulses 💅

✨ NAME ✨

struct ath_dfs_stats — DFS Statistics per wiphy 🦋

✨ SYNOPSIS ✨

struct ath_dfs_stats {
    u32 pulses_total;
    u32 pulses_no_dfs;
    u32 pulses_detected;
    u32 datalen_discards;
    u32 rssi_discards;
    u32 bwinfo_discards;
    u32 pri_phy_errors;
    u32 ext_phy_errors;
    u32 dc_phy_errors;
    u32 pulses_processed;
    u32 radar_detected;
 };

not me just listing every single member for u, bestie — no skips, no cap 🫶

✨ Members ✨

• pulses_total — pulses reported by HW. that's the raw hardware count, the source of truth, the main character 👑
• pulses_no_dfs — pulses that were wrongly reported as DFS. awk. not DFS, but they still showed up like they belonged 💀
• pulses_detected — pulses detected so far ✨
• datalen_discards — pulses discarded because the datalen was invalid 🙈
• rssi_discards — pulses discarded because the RSSI was invalid 😭
• bwinfo_discards — pulses discarded because the BW info was invalid 🍓
• pri_phy_errors — pulses reported for the primary channel
• ext_phy_errors — pulses reported for the extension channel
• dc_phy_errors — pulses reported for primary + extension channel (both at once, multitasking icon 💅)
• pulses_processed — pulses forwarded to the detector ✨
• radar_detected — radars detected 🔥 the moment this number goes up, it's a whole situation
