STRUCT WIPHY_WOWLAN_SUPPORT(9)

📦 version 7.3.1, in nixpkgs unstable

💖 NAME 💖

okay so this is the struct wiphy_wowlan_support(9) page, bestie — the Kernel API Manual entry for struct wiphy_wowlan_support - WoWLAN support data. yes, WoWLAN. wake-on-wireless-LAN. it’s giving “your Wi-Fi can wake the whole system up” main character energy ✨

🌸 SYNOPSIS 🌸

here’s the struct in all its iconic glory, copied exactly so nobody gets any funny ideas:

struct wiphy_wowlan_support {
    u32 flags;
    int n_patterns;
    int pattern_max_len;
    int pattern_min_len;
    int max_pkt_offset;
    int max_nd_match_sets;
    const struct wiphy_wowlan_tcp_support *tcp;
 };

🎀 Members 🎀

  • flags — see enum wiphy_wowlan_support_flags 👑 that’s where the flag lore lives.
  • n_patterns — the number of supported wakeup patterns. and like, see nl80211.h for the pattern definition, iykyk 💅
  • pattern_max_len — maximum length of each pattern. big pattern energy 🦋
  • pattern_min_len — minimum length of each pattern. tiny pattern energy 🍓
  • max_pkt_offset — maximum Rx packet offset. noted, stored, slayed ✨
  • max_nd_match_sets — maximum number of matchsets for net-detect. it’s similar, but not necessarily identical, to max_match_sets for scheduled scans. see struct cfg80211_sched_scan_request.match_sets for more details, bestie 📚
  • tcp — TCP wakeup support information. yes, TCP has entered the wakeup chat 💀🔥

Like, first things first: the whole thing lives in the kernel file ./include/net/cfg80211.h, and then it's just… the entire extended friend group of cfg80211 and mac80211 entries. Every single one of them gets a mention, and yes, I'm listing all of them, because we don't do "etc." in this house 💅

  • Kernel file ./include/net/cfg80211.h Introduction(9), Device registration(9)

Okay so the intro and registration pages are your entry point, and from there it just spirals into channel/rate/bss-type territory:

The work-queue extended universe (regular, delayed, hrtimer — the full set, no skips):

AP reg power + wireless_dev + the wdev helpers:

Utility functions — the little helpers that ate 💅

Radio range validity + channel-allowed checks:

Radiotap + header length helpers:

Data path helpers — the plumbing, and honestly it's kind of the moment 🔥

The element/IE finder family (match, elem, ie, ext, vendor — all of them):

RNR iteration + defrag + layer2 update:

Regulatory enforcement infrastructure and the internal regdb functions — the rules girlies 💜

Scan-done + BSS informing + the __-prefixed one (yes, __cfg80211_get_bss, keep both underscores, we respect the prefix):

BSS get/ref/put/unlink/iter — the whole custody arrangement:

MLME rx/tx + auth timeout + assoc resp/failure:

RFkill integration:

Vendor commands:

Test mode:

Connect/roam/disconnect notification squad 🦋

Remain-on-channel + mgmt tx expiry:

Station info alloc/release + new/del sta:

Rx info + mgmt rx (ext and khz variants included, always):

Tx status + control port:

CQM notifications (rssi, pktloss, txe, beacon loss — collect them all):

Radar/CAC + misc notifications, including the double-underscore radar one:

Spurious/unexpected frames + probe status + OBSS beacon reporting:

And the list is still going, because of course it is:

  • struct cfg80211_beaconing_check_config(9)

okay so the reference list keeps going — this is the long tail of the SEE ALSO section, and honestly it's giving "the whole kernel networking group chat got added to the list" 💅 every single one of these is a real page and every single one is staying, so let's get through them together 🫶

the regulatory beaconing girlies 🌸

channel switch announce squad 📣

operating class + chandef conversions (the math besties) 🧮

TDLS + bitrate ✨

register / unregister the device crew 🎀

FT events, P2P attrs, IE splitting 🦋

NAN, auth, PMSR, and friends 💜

colors + 6GHz + MLO (the newer gen) 🌈

more NAN (she's everywhere, and honestly? iconic) 🧚

debugfs + S1G + the very last one 🍓

and that's the whole list, bestie — every single cross-reference, no skips, no cap 💖 take a sip of water, you earned it 🫶

lowkey reminder: these are references to other pages, not extra options on this struct — don't go looking for them in the SYNOPSIS or anything 🙈

okay and before you close the tab: this page lives in ./include/net, it's dated October 2026, and its title is struct wiphy_wowlan_support(9) — so if you're citing it or linking it in your notes, that's the whole receipt ✨ mwah, go ship something great 💅👑
