STRUCT IEEE80211_STA_UHR_CAP(9)

👑 struct ieee80211_sta_uhr_cap — the kernel API manual, bestie edition 💅

okay so like, welcome to the <pink>struct ieee80211_sta_uhr_cap(9)</pink> page — yes that's the manual name, section 9, kernel API manual energy, we're literally in the big leagues now 🎀

this is part 1 of 3, so hydrate, stretch, and do not scroll away, because there is more coming and it's all important, no cap ✨

🌸 NAME 🌸

struct ieee80211_sta_uhr_cap — the STA's UHR capabilities 💖

like, it's the little struct that holds what a station can actually do with UHR. her whole personality in one C struct, fr fr.

🦋 SYNOPSIS 🦋

struct ieee80211_sta_uhr_cap {
    bool has_uhr;
    struct ieee80211_uhr_cap_mac mac;
    struct ieee80211_uhr_cap_phy phy;
 };

look at her. three members. immaculate. the way this struct is shaped is honestly iconic 🫶

✨ Members ✨

has_uhr — a bool that's true iff UHR is supported and the data is valid. like, if this is false, the rest of the struct is giving "no thoughts head empty" and you should not be trusting it 😭 iff means if and only if btw, iykyk 💀
mac — the fixed MAC capabilities, typed as struct ieee80211_uhr_cap_mac. MAC layer stuff, staying in its lane, slaying 💅
phy — the fixed PHY capabilities, typed as struct ieee80211_uhr_cap_phy. physics layer bestie, also staying in its lane 🔥

⚠️ lowkey important: has_uhr being false means the data isn't valid — so don't go reading mac and phy like they're facts, because that's a vibe check they will fail 🙈

part 2 is coming, stay tuned bestie, we're not done yet 🌈

✨ SEE ALSO ✨

okay bestie, if you wanna go down the rabbit hole (and honestly, same), here's the full SEE ALSO squad.

mwah, go touch some kernel code bestie ✨🦋
