STRUCT RATE_INFO(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

struct rate_info — literally just bitrate information, bestie. That's the whole vibe ✨

(you're reading the struct rate_info(9) page from the Kernel API Manual, and yes she's that girl 🎀)

🦋 SYNOPSIS 🦋

okay so here's the struct in all her glory, copy it exactly, no cap:

struct rate_info {
    u16 flags;
    u16 legacy;
    u8 mcs;
    u8 nss;
    u8 bw;
    u8 he_gi;
    u8 he_dcm;
    u8 he_ru_alloc;
    u8 n_bonded_ch;
    u8 eht_gi;
    u8 eht_ru_alloc;
 };

🌸 Members 🌸

time to meet the whole squad, one field at a time 🫶

  • flags — a bitflag situation, made of flags from enum rate_info_flags 💅
  • legacy — the bitrate in 100kbit/s for 802.11abg (old money, but iconic)
  • mcs — the mcs index, but only if this struct is describing an HT/VHT/HE/EHT/S1G/UHR rate. she's conditional, she's mysterious 🙈
  • nss — number of streams (VHT & HE only, don't @ me)
  • bw — bandwidth, straight from enum rate_info_bw
  • he_gi — HE guard interval, from enum nl80211_he_gi
  • he_dcm — the HE DCM value
  • he_ru_alloc — HE RU allocation, from enum nl80211_he_ru_alloc — and heads up, this one is only valid if bw is RATE_INFO_BW_HE_RU ⚠️
  • n_bonded_ch — in case of EDMG, the number of bonded channels, which is 1-4
  • eht_gi — EHT guard interval, from enum nl80211_eht_gi
  • eht_ru_alloc — EHT RU allocation, from enum nl80211_eht_ru_alloc — same deal, only valid if bw is RATE_INFO_BW_EHT_RU ⚠️

✨ Description ✨

It's information about a receiving or transmitting bitrate. that's it, that's the whole personality 💖

✨ SEE ALSO ✨

okay so bestie, fair warning: this SEE ALSO is huge. like, the entire cfg80211 cinematic universe showed up to the group chat at once 💀 but every single one is a real page and i'm not skipping a single one, so buckle up, no cap.

  • Kernel file ./include/net/cfg80211.h Introduction(9) — the origin story, the mothership, the file this whole struct lives in.
  • Device registration(9) — how devices get themselves onto the guest list.

🎀 the channel + rate era

  • enum ieee80211_channel_flags(9), struct ieee80211_channel(9), enum ieee80211_rate_flags(9), enum ieee80211_bss_type(9), enum ieee80211_privacy(9), struct ieee80211_rate(9) — the classic lineup, channels and rates and their little flag enums, iconic behaviour only.
  • struct ieee80211_he_obss_pd(9), struct cfg80211_he_bss_color(9) — HE-era stuff, spatial reuse vibes 🌸
  • struct ieee80211_sta_ht_cap(9), struct ieee80211_sta_vht_cap(9), struct ieee80211_sta_he_cap(9), struct ieee80211_eht_mcs_nss_supp(9), struct ieee80211_sta_eht_cap(9), struct ieee80211_sta_uhr_cap(9) — the whole capability glow-up chain, HT → VHT → HE → EHT → UHR, they grow up so fast 😭
  • struct ieee80211_sband_iftype_data(9), enum ieee80211_edmg_bw_config(9), struct ieee80211_edmg(9), struct ieee80211_sta_s1g_cap(9), struct ieee80211_supported_band(9) — bands and iftypes and EDMG/S1G energy.
  • _ieee80211_set_sband_iftype_data(9), ieee80211_set_sband_iftype_data(9), for_each_sband_iftype_data(9), ieee80211_get_sband_iftype_data(9) — the underscore one is the internals, the no-underscore one is the "please use me" one, and yes i'm obsessed with how that's just a thing. ✨
  • ieee80211_get_he_iftype_cap(9), ieee80211_get_he_6ghz_capa(9), ieee80211_get_eht_iftype_cap(9), ieee80211_get_uhr_iftype_cap(9), wiphy_read_of_freq_limits(9) — getters, getters, getters, plus a little device-tree frequency-limits moment.

aaaand that's the whole list, every last one, zero skips 💖

okay the cross-reference list is long and we're still going, bestie — grab a snack, we're finishing the scroll 💅

that's the whole list, bestie — 64 cross-refs deep and we made it 🫶 no skipping, every single one accounted for.
