STRUCT STA_OPMODE_INFO(9)

📦 version 7.3.1, in nixpkgs unstable

💖 struct sta_opmode_info — Kernel API Manual ✨

okay bestie, gather round, because we're doing kernel structs today and honestly? this one's a little cutie. it's called struct sta_opmode_info and it's literally just the station's ht/vht operation mode information, all bundled up in one vibe. 🦋

🌸 NAME 🌸

struct sta_opmode_info — Station's ht/vht operation mode information

like, that's the whole thing. the ht/vht operation mode info. for a station. no cap. 💅

✨ SYNOPSIS ✨

struct sta_opmode_info {
    u32 changed;
    enum nl80211_smps_mode smps_mode;
    enum nl80211_chan_width bw;
    u8 rx_nss;
 };

there she is. four little members, living their best lives. copy it exactly, don't get cute with it. 🎀

🧚 Members 🧚

  • changed — this one contains a value from enum wiphy_opmode_flag. that's it, that's the whole job. it's the "what actually changed" field, and it gets its values from that enum. ⭐
  • smps_mode — the new SMPS mode value of a station, straight from enum nl80211_smps_mode. new SMPS mode. of a station. said it once and I'll say it again, because that's what it is. 🔥
  • bw — the new max bandwidth value of a station, from enum nl80211_chan_width. it's giving "bigger bandwidth, better vibes". 😭 (okay the vibes part is me, the bandwidth-from-that-enum part is the manpage, keep that.)
  • rx_nss — the new rx_nss value of a station. it's a u8, it's new, it belongs to a station. icon behavior, honestly. 👑

that's part one, and there's more coming so don't go anywhere — we're literally just getting started. 🫶

🌸 SEE ALSO 🌸

okay bestie, this is the part where the page hands you the whole friend group. the kernel file is ./include/net/cfg80211.h, and every single (9) bestie below is invited to the group chat. no cap, nothing got left on read — even the absurdly long names 💅

…and the rest of the guest list 💅 — literally every single one of these has its own page, so if you get lost, just go tap on one:

okay that's the regulatory/channel/device-registration corner of the universe, we're moving on ✨

IE splitting, WoWLAN wakeups, and the combo-checker crew — the combo checker is lowkey the main character of "can I actually do this" ngl 🫶

NAN, PMSR, OWE, BSS coloring… yes bestie the whole alphabet of Wi-Fi drama is here 💀

6 GHz power types, MLO reconfig, S1G frequency math and debugfs read/write — the deep lore. iykyk 🔥

and that's a wrap on struct sta_opmode_info(9) 🎀
