ENUM NL80211_TXQ_STATS(9)

📦 version 7.3.1, in nixpkgs unstable

💅 enum nl80211_txq_stats 💅

okay so this is a page from the Kernel API Manual, section 9 — yes, section 9, the big-kid kernel section 💖 — and it's all about enum nl80211_txq_stats, aka the per TXQ statistics attributes. if you've ever wondered "what numbers can i get back about this transmit queue", bestie, this is literally the whole menu 🎀

✨ NAME ✨

enum nl80211_txq_stats — per TXQ statistics attributes 🦋

like, every attribute that can show up in a TXQ stats dump. that's the vibe.

🌸 SYNOPSIS 🌸

enum nl80211_txq_stats {
    __NL80211_TXQ_STATS_INVALID ,
    NL80211_TXQ_STATS_BACKLOG_BYTES ,
    NL80211_TXQ_STATS_BACKLOG_PACKETS ,
    NL80211_TXQ_STATS_FLOWS ,
    NL80211_TXQ_STATS_DROPS ,
    NL80211_TXQ_STATS_ECN_MARKS ,

    NUM_NL80211_TXQ_STATS ,
    NL80211_TXQ_STATS_MAX

};

look at her. fourteen constants, all lined up, all iconic 👑

🧚 CONSTANTS 🧚

💫 the whole roster, one by one

  • __NL80211_TXQ_STATS_INVALID — attribute number 0 is reserved. like, hands off, that one's taken 🙈
  • NL80211_TXQ_STATS_BACKLOG_BYTES — how many bytes are currently backlogged 📦
  • NL80211_TXQ_STATS_BACKLOG_PACKETS — how many packets are currently backlogged 🎀
  • NL80211_TXQ_STATS_FLOWS — the total number of new flows seen 🌊
  • NL80211_TXQ_STATS_DROPS — total number of packet drops 💀 rip little packets
  • NL80211_TXQ_STATS_ECN_MARKS — total number of packet ECN marks 🖍️
  • NL80211_TXQ_STATS_OVERLIMIT — number of drops because the queue space overflowed 🫠
  • NL80211_TXQ_STATS_OVERMEMORY — number of drops because the memory limit overflowed. heads up: only for per-phy stats ⚠️ like, per-phy only, don't @ me
  • NL80211_TXQ_STATS_COLLISIONS — number of hash collisions 💥
  • NL80211_TXQ_STATS_TX_BYTES — total number of bytes dequeued from the TXQ 📤
  • NL80211_TXQ_STATS_TX_PACKETS — total number of packets dequeued from the TXQ 📨
  • NL80211_TXQ_STATS_MAX_FLOWS — number of flow buckets for the PHY 🪣
  • NUM_NL80211_TXQ_STATS — number of attributes here 🔢 (the count, not an attribute)
  • NL80211_TXQ_STATS_MAX — highest numbered attribute here 🔝
fr fr bestie, __NL80211_TXQ_STATS_INVALID being 0-and-reserved is a whole thing — it's the sentinel, not a stat. don't go reading it like it means something 🙅‍♀️
