STRUCT IEEE80211_TXQ_PARAMS(9)

📦 version 7.3.1, in nixpkgs unstable

💖 struct ieee80211_txq_params(9) — TX queue parameters 💖

okay so bestie, this is from the Kernel API Manual, and it's literally the struct for TX queue parameters. no cap, every field is right here, and we are keeping all the facts exactly as they are ✨

🌸 NAME 🌸

struct ieee80211_txq_params — TX queue parameters

🦋 SYNOPSIS 🦋

struct ieee80211_txq_params {
    enum nl80211_ac ac;
    u16 txop;
    u16 cwmin;
    u16 cwmax;
    u8 aifs;
    int link_id;
};

👑 Members 👑

  • ac — AC identifier. that's the whole vibe, periodt 💅
  • txop — Maximum burst time in units of 32 usecs, with 0 meaning disabled. yes bestie, zero is the off switch 🔥
  • cwmin — Minimum contention window. the value is of the form 2^n-1, in the range 1..32767 🎀
  • cwmax — Maximum contention window. same shape: a value of the form 2^n-1, in the range 1..32767 ✨
  • aifs — Arbitration interframe space, in the range [0..255] 🦋
  • link_id — link_id, or -1 for non-MLD. iykyk 💜

and then the entire wiphy lifecycle clique, honestly obsessed with how thorough this is 💀:

(both the regular and the _hrtimer_ variants, she did not skip a single one 👑)

plus the wireless-dev set:

then the Utility functions toolbox, literally the "just vibes and helpers" section 🌸:

and the Data path helpers, the "moving actual packets around" squad 🔥:

regulatory besties, assemble 🎀:

then the whole BSS-notification and MLME pipeline, it's giving "events, events, events" ✨:

and the mlme + connection-event crew:

RFkill integration, small but slay:

Vendor commands, for when you gotta do your own thing 💅:

Test mode, the lab-girlie era 🧪 (well, no emoji promises — just test mode):

and then the giant tail end — connection responses, roaming, station events, mgmt rx/tx, cqm, radar, cac, gtk rekey, all of it 💖:

like, that's the whole extended universe bestie 😭 every single one of them is a real page you can go read, and honestly? reading them all is a flex. take your time, hydrate, and don't forget — this list is the see also, so it's basically the "if you liked this page you'll also like…" of the kernel 🌟

okay bestie, the guest list for this section is long — like, the whole friend group showed up. here's every single one, no skips:

the regulatory + channel crew 🦋 ngl this little block is giving "who's allowed to beacon" energy and honestly? iconic.

interfaces, links, and feature flags — the admin friend group fr fr. stopping things is a whole vibe.

NAN girlies rise up ✨ plus auth, PMSR, and the assoc comeback — yes she did come back, and she brought cfg80211_update_owe_info_event(9) as a plus-one.

the whole colour-change notif squad 🎀 started, aborted, notify — she's dramatic and we love her. plus 6GHz power type, MLO reconfig, and cfg80211_epcs_changed(9) just existing quietly iykyk.

and closing out: more NAN (cluster joined!! 💜), the locked debugfs read/write duo, the S1G freq crew, and cfg80211_incumbent_signal_notify(9) holding the door. periodt.

that's the whole 64-reference guest list bestie, nobody got left outside 🫶 this page lives in the ./include/net corner of the tree, dated October 2026 — so if you're reading it, congrats, you're early and you're slaying 💅 go read a couple of these, they're all (9)s so you know they're kernel-API royalty 👑
