STRUCT IEEE80211_STA_HE_CAP(9)

📦 version 7.3.1, in nixpkgs unstable

🌸 NAME 🌸

okay so bestie, welcome to the struct ieee80211_sta_he_cap(9) page from the Kernel API manual — this is literally the vibe check for a STA's HE capabilities 💅

struct ieee80211_sta_he_cap — a STA's HE capabilities, no cap ✨

✨ SYNOPSIS ✨

struct ieee80211_sta_he_cap {
    bool has_he;
    struct ieee80211_he_cap_elem he_cap_elem;
    struct ieee80211_he_mcs_nss_supp he_mcs_nss_supp;
    u8 ppe_thres[IEEE80211_HE_PPE_THRES_MAX_LEN];
 };

🎀 Members 🎀

  • has_he — it's a bool, and it's true iff (that's "if and only if", bestie 🫶) the HE data is valid. so like, if this is false, don't go trusting the rest of the struct, mkay? 🚩
  • he_cap_elem — the fixed portion of the HE capabilities element. it's a struct ieee80211_he_cap_elem, and it's giving "the part that doesn't move" energy 🎀
  • he_mcs_nss_supp — this one is a struct ieee80211_he_mcs_nss_supp, and it holds the supported NSS/MCS combinations. iconic combo breakdown behavior, honestly 👑
  • ppe_thres — it's a u8 array sized IEEE80211_HE_PPE_THRES_MAX_LEN, and it holds the PPE Thresholds data. yes, the whole array, not just a lil pointer — she's substantial 💖

💅 Description 💅

okay so this struct is literally the main character when it comes to describing the most essential parameters you need for 802.11ax HE capabilities for a STA. like, this is the core info — not every tiny detail, but the stuff that actually matters for the HE capabilities conversation 🔥

think of it as the group chat where has_he decides if anyone's even online, he_cap_elem brings the fixed portion of the HE capabilities element, he_mcs_nss_supp spills the supported NSS/MCS combinations, and ppe_thres shows up with the PPE Thresholds data. all four of them, together, running the 802.11ax HE capabilities narrative for a STA 💫

more deets are coming in the next part, so don't go anywhere — this page is long and we're only getting started 🦋

💅 SEE ALSO 💅

okay bestie, this is the part where the manpage basically says “go read the entire kernel group chat” 😭 and honestly? iconic. the kernel file is ./include/net/cfg80211.h, and here’s every single see-also bestie in the order the page lists them:

…and then the guest list keeps going, because obviously it does 💅 here's the rest of the SEE ALSO crew, no cap, every single one of them:

okay bestie that's the whole thing, you're officially a HE capabilities girlie now 🎀 go forth and git grep responsibly 🫶
