STRUCT IEEE80211_HE_OBSS_PD(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’– struct ieee80211_he_obss_pd(9) β€” the kernel API manual, bestie edition πŸ’–

okay so you're looking at struct ieee80211_he_obss_pd from the (9) kernel API manual and honestly? it's giving spatial reuse realness. this little struct is literally the whole vibe of your AP settings for spatial reuse, and we're gonna go through it field by field like we're deep in the group chat at 2am. no cap, every single member is in here. ✨


🌸 NAME 🌸

struct ieee80211_he_obss_pd β€” AP settings for spatial reuse πŸ¦‹


πŸŽ€ SYNOPSIS πŸŽ€

struct ieee80211_he_obss_pd {
    bool enable;
    u8 sr_ctrl;
    u8 non_srg_max_offset;
    u8 min_offset;
    u8 max_offset;
    u8 bss_color_bitmap[8];
    u8 partial_bssid_bitmap[8];
 };

look at her. seven whole fields. main character energy, fr fr. πŸ’…


πŸ‘‘ Members πŸ‘‘

  • enable β€” is the feature enabled. that's it, that's the whole field. a bool doing the most important job: yes or no, on or off, slay or nay. 🫢
  • sr_ctrl β€” The SR Control field of SRP element. yes it's a u8, yes it's iconic, yes it holds that SR Control field. πŸ‘‘
  • non_srg_max_offset β€” non-SRG maximum tx power offset. not "the" max, the non-SRG max. keep them straight bestie, iykyk. ✨
  • min_offset β€” minimal tx power offset an associated station shall use. shall, not should. the manual said what it said. πŸ’…
  • max_offset β€” maximum tx power offset an associated station shall use. the ceiling of the situation. the limit of the limit. πŸ”₯
  • bss_color_bitmap β€” bitmap that indicates the BSS color values used by members of the SRG. it's a u8 array, 8 of them, living its best bitmap life. 🌈
  • partial_bssid_bitmap β€” bitmap that indicates the partial BSSID values used by members of the SRG. also u8[8], also doing bitmaps, also absolutely eating. πŸ“
side note bestie: both of those bitmaps are literally u8 arrays of size 8 β€” don't come for me, that's exactly what the page says. 🧚

okay that's the whole struct layout and every member, no details dropped, no fields skipped β€” part 2 is coming so don't go anywhere πŸ’œ

Okay bestie, this is the part where the page just points at everyone else β€” it's giving "let me introduce you to my entire friend group" energy 😭 and honestly every single one of them is a real one. Nothing skipped, nothing merged, all names exactly as they appear. Let's go πŸ’…
