STRUCT ATH5K_ANI_STATE(9)

💖 struct ath5k_ani_state(9) — ANI state and associated counters 💖

okay bestie, welcome to the Kernel API Manual page for struct ath5k_ani_state(9) ✨. It’s giving “one struct holding the ANI state plus the associated counters,” and we’re gonna go through every single field because we don’t skip, ever 💅.

💅 NAME 💅

struct ath5k_ani_state — the ANI state and associated counters, no cap 🫶.

✨ SYNOPSIS ✨

struct ath5k_ani_state {
    enum ath5k_ani_mode     ani_mode;
    int noise_imm_level;
    int spur_level;
    int firstep_level;
    bool ofdm_weak_sig;
    bool cck_weak_sig;
    int max_spur_level;
    unsigned int            listen_time;
    unsigned int            ofdm_errors;
    unsigned int            cck_errors;
    struct ath_cycle_counters last_cc;

• noise_imm_level — the noise immunity level, periodt 💅
• spur_level — the spur immunity level ✨
• firstep_level — the FIRstep level 🎀
• ofdm_weak_sig — the OFDM weak signal detection state, aka on/off 🦋
• cck_weak_sig — the CCK weak signal detection state, aka on/off 🌸
• max_spur_level — the max spur immunity level, and it’s chip-specific 💀

• ofdm_errors — the OFDM timing error count 🔥
• cck_errors — the CCK timing error count 🌈
• last_cc — the struct ath_cycle_counters from last time, for stats 💁
• last_listen — the listen time from the previous run, for stats 💜
• last_ofdm_errors — the OFDM timing error count from the previous run, for tats — yes, “tats,” that’s what the original says, we keep it 😭
