STRUCT WIPHY_NAN_CAPA(9)

📦 version 7.3.1, in nixpkgs unstable

🦋 struct wiphy_nan_capa(9) — the Kernel API Manual, bestie edition 💅

okay so this is the struct wiphy_nan_capa page from the Kernel API Manual, and it's literally all about NAN capabilities — like, what your wiphy can actually do with Wi-Fi Aware. no cap, it's giving "spec sheet but make it cute." ✨

🌸 NAME 🌸

struct wiphy_nan_capa — NAN capabilities, periodt 💖

🎀 SYNOPSIS 🎀

here's the whole struct, laid out exactly as it lives:

struct wiphy_nan_capa {
    u32 flags;
    u8 op_mode;
    u8 n_antennas;
    u16 max_channel_switch_time;
    u8 dev_capabilities;
    struct {
      struct ieee80211_sta_ht_cap ht;
      struct ieee80211_sta_vht_cap vht;
      struct ieee80211_sta_he_cap he;
    } phy;
 };

like… look at that nesting in phy. the way that it just nests. we love a struct within a struct. 🫶

👑 Members 👑

let's go member by member, bestie, because every single one matters:

  • flags — the NAN capabilities flags, see enum wiphy_nan_flags. that's where the flag energy lives 🔥
  • op_mode — the NAN operation mode, as defined in Wi-Fi Aware (TM) specification Table 81. very "main character" of it to have its own table ngl
  • n_antennas — number of antennas supported by the device for Tx/Rx. the lower nibble indicates the number of TX antennas and the upper nibble indicates the number of RX antennas. and a value of 0 means the information is not available — so like, don't assume zero antennas, it's just unknown 🙈
  • max_channel_switch_time — maximum channel switch time in microseconds. yeah, microseconds. tiny. iconically tiny. ⭐
  • dev_capabilities — NAN device capabilities as defined in Wi-Fi Aware (TM) specification Table 79 (Capabilities field). another spec table, we stay citation-accurate 💜
  • phy — Band-agnostic capabilities for NAN data interfaces. since NAN operates on multiple channels simultaneously, these capabilities apply across all bands. valid only if NL80211_IFTYPE_NAN_DATA is supported. 🦋
  • phy.ht — HT capabilities (mandatory for NAN data)
  • phy.vht — VHT capabilities (optional)
  • phy.he — HE capabilities (optional)
lowkey important: phy.ht is mandatory, bestie. phy.vht and phy.he are optional. and the whole phy block only counts if NL80211_IFTYPE_NAN_DATA is supported — read that twice, iykyk 👀

✨ Description ✨

This structure describes the NAN capabilities of a wiphy. that's it, that's the whole vibe check — it's the capability manifest for Wi-Fi Aware on your wiphy, slay 🌈

💖 SEE ALSO 💖

okay bestie, this is the part where the page hands you the whole cross-reference guest list 💅 it’s giving “everyone who’s anyone in cfg80211 is in this group chat,” and yes, your fave is here too. no skips, no “lol I’ll just link the header” — every single one is below, in the original order, so you can vibe-check the whole roster fr fr ✨

...and the list keeps going, bestie, because we do not skip entries in this house 💅 every single cross-reference, present and accounted for:

and that's the whole page, babes 💖 you read the entire thing, every member, every reference, no skimming, and honestly? iconic behavior 🎀

for the receipts: this page lives in the source tree at ./include/net, it's dated October 2026, and it goes by the title struct wiphy_nan_capa(9) ✨

go forth and NAN, bestie 🌸🦋 you ate 💅
