🎀 Constants 🎀

  • IEEE80211_CHAN_DISABLED — this channel is disabled. 🚫
  • IEEE80211_CHAN_NO_IR — do not initiate radiation; this includes sending probe requests or beaconing. 🙈
  • IEEE80211_CHAN_PSD — Power spectral density (in dBm) is set for this channel. ✨
  • IEEE80211_CHAN_RADAR — radar detection is required on this channel. 📡
  • IEEE80211_CHAN_NO_HT40PLUS — the extension channel above this channel is not permitted. 🚫
  • IEEE80211_CHAN_NO_HT40MINUS — the extension channel below this channel is not permitted. 🚫
  • IEEE80211_CHAN_NO_OFDM — OFDM is not allowed on this channel. 💀
  • IEEE80211_CHAN_NO_80MHZ — if the driver supports 80 MHz on the band, this flag indicates that an 80 MHz channel cannot use this channel as the control or any of the secondary channels. This may be due to the driver or due to regulatory bandwidth restrictions. 📛
  • IEEE80211_CHAN_NO_160MHZ — if the driver supports 160 MHz on the band, this flag indicates that a 160 MHz channel cannot use this channel as the control or any of the secondary channels. This may be due to the driver or due to regulatory bandwidth restrictions. 📛
  • IEEE80211_CHAN_INDOOR_ONLY — see NL80211_FREQUENCY_ATTR_INDOOR_ONLY. 🏠
  • IEEE80211_CHAN_IR_CONCURRENT — see NL80211_FREQUENCY_ATTR_IR_CONCURRENT. 👀
  • IEEE80211_CHAN_NO_20MHZ — 20 MHz bandwidth is not permitted on this channel. 🚫
  • IEEE80211_CHAN_NO_10MHZ — 10 MHz bandwidth is not permitted on this channel. 🚫
  • IEEE80211_CHAN_NO_HE — HE operation is not permitted on this channel. 💀
  • IEEE80211_CHAN_NO_UHR — UHR operation is not permitted on this channel. 💀
  • IEEE80211_CHAN_NO_320MHZ — if the driver supports 320 MHz on the band, this flag indicates that a 320 MHz channel cannot use this channel as the control or any of the secondary channels. This may be due to the driver or due to regulatory bandwidth restrictions. 📛
  • IEEE80211_CHAN_NO_EHT — EHT operation is not permitted on this channel. 💀
  • IEEE80211_CHAN_DFS_CONCURRENT — See NL80211_RRF_DFS_CONCURRENT. 👀
  • IEEE80211_CHAN_NO_6GHZ_VLP_CLIENT — Client connection with VLP AP not permitted using this channel. 🚫
  • IEEE80211_CHAN_NO_6GHZ_AFC_CLIENT — Client connection with AFC AP not permitted using this channel. 🚫
  • IEEE80211_CHAN_CAN_MONITOR — This channel can be used for monitor mode even in the presence of other (regulatory) restrictions, even if it is otherwise disabled. 👑 This one's kind of iconic.
  • IEEE80211_CHAN_ALLOW_6GHZ_VLP_AP — Allow using this channel for AP operation with very low power (VLP), even if otherwise set to NO_IR. ✅
  • IEEE80211_CHAN_ALLOW_20MHZ_ACTIVITY — Allow activity on a 20 MHz channel, even if otherwise set to NO_IR. ✅
  • IEEE80211_CHAN_S1G_NO_PRIMARY — Prevents the channel for use as an S1G primary channel. Does not prevent the wider operating channel described by the chandef from being used. In order for a 2MHz primary to be used, both 1MHz subchannels shall not contain this flag. 🧚
  • IEEE80211_CHAN_NO_4MHZ — 4 MHz bandwidth is not permitted on this channel. 🚫
  • IEEE80211_CHAN_NO_8MHZ — 8 MHz bandwidth is not permitted on this channel. 🚫
  • IEEE80211_CHAN_NO_16MHZ — 16 MHz bandwidth is not permitted on this channel. 🚫

💖 Description 💖

Channel flags set by the regulatory control code. That's the whole vibe — regulatory control code is the one setting these flags. 👑

and that's the whole see-also guest list, bestie — literally every single one of them made it to the party 🎉 no plus-ones were cut, I promise.

...and the see-also list literally keeps going, bestie, so buckle up — here's the rest of it, exactly as it's written, no cap:

okay so that's the whole list, every single one, and yes the NAN and S1G and MLO girlies all showed up to the party 💅✨ like the sheer volume of cross-references is giving "everyone in the wireless group chat got @'d" and honestly? iconic. go read whichever one your heart desires, they're all linked right there in the manual, iykyk 🫶

reminder bestie: I didn't invent a single one of these — if a name isn't in the list above, it's not in the real page either. don't come for me, come for the kernel 😭

and that's a wrap on the whole page, fr fr 🎀 this lil section came from ./include/net in the October 2026 build — so if you're reading this, say hi to the source tree for me and go touch some grass (or, like, at least go touch a struct). bye bestie, mwah 💖🦋🌸
