STRUCT TXQ_INFO(9)

💖 NAME 💖

welcome to the Kernel API Manual page for struct txq_info(9), bestie — it's a per tid queue. that's the whole name, and it's literally a per tid queue 💅.

✨ SYNOPSIS ✨

okay so here's the exact struct, and yes every field is staying because we do not skip:

struct txq_info {
    struct fq_tin tin;
    struct codel_vars def_cvars;
    struct codel_stats cstats;
    u16 schedule_round;
    struct list_head schedule_order;
    struct sk_buff_head frags;
    unsigned long flags;
    struct ieee80211_txq txq;
 };

🎀 Members 🎀

vibe check on each member, no cap:

• tin — contains packets split into multiple flows. it's the part holding packets that got split into multiple flows, and that's lowkey the whole point. 🦋
• def_cvars — codel vars for the tin's default_flow. these are the codel vars for the tin's default_flow, exactly as stated. 🫶
• cstats — code statistics for this queue. keeping the code statistics for this queue — periodt. 💖
• schedule_round — counter to prevent infinite loops on TXQ scheduling. it's the counter that keeps TXQ scheduling from infinite-looping, highkey crucial. 🔥
• schedule_order — used with ieee80211_local->active_txqs. no extra lore: it's used with ieee80211_local->active_txqs.
• frags — used to keep fragments created after dequeue. literally used to keep fragments created after dequeue. 🎀
• flags — TXQ flags from enum txq_info_flags. all the TXQ flags from enum txq_info_flags, fr fr.
• txq — the driver visible part. the driver visible part, aka the part the driver gets to see 👑.
