ieee80211_data_to_8023(9)

📦 version 7.3.1, in nixpkgs unstable

💖 ieee80211_data_to_8023 — Kernel API Manual, bestie edition 💖

okay so welcome to ieee80211_data_to_8023(9), a real one from the Kernel API Manual. this is the ✨glow-up✨ page where we take an 802.11 data frame and turn it into an 802.3 one. yes it's a conversion glow-up. no cap. 🦋

🌸 NAME 🌸

ieee80211_data_to_8023 — convert an 802.11 data frame to 802.3

like, it literally says it right there. 802.11 goes in, 802.3 comes out. the transformation is giving main character energy. 💅

✨ SYNOPSIS ✨

int ieee80211_data_to_8023(struct sk_buff *skb, const u8 *addr, enum
nl80211_iftype iftype);

that's the whole signature, bestie — returns an int, takes three args. screenshot it, put it on your wall. 🎀

🎀 ARGUMENTS 🎀

  • skb — the 802.11 data frame. this is the one getting converted. the little guy. the subject of the makeover. 🙈
  • addr — the device MAC address. yes, that MAC address. the hardware's whole identity. 👑
  • iftype — the virtual interface type. it's an enum nl80211_iftype, so it's a whole vibe check of a value. 🌈

🔥 RETURN 🔥

  • 0 on success. slay. 🫶
  • Non-zero on error. not slay, but at least it tells you. 💀

okay that's part one down, and there's more pages coming so don't go anywhere — stay tuned, we're literally not done. 💜

💅 SEE ALSO 💅

okay bestie, brace yourself — the SEE ALSO on this page is not a little list, it's a whole syllabus 😭. Everything below lives in the kernel file ./include/net/cfg80211.h (that's the mothership, the main character), and every single one of these pages is linked and real. I'm not skipping a single one, so grab a snack 🍓.

🎀 the file itself, the intros, and the band/cap besties

✨ Actions and configuration — the channel-definition girlies

the way this next block is basically nothing but chandef this and chandef that 🫶 like yes queen, define your channel:

🌈 Utility functions — the little helpers that ate

🧚 Data path helpers — hi bestie, these are YOUR people

lowkey this is the group our page hangs out with, so show some respect 💅:

👑 Regulatory enforcement infrastructure (& the internal db girlies)

⭐ scan results, BSS bookkeeping and MLME moments

💀 RFkill, vendor commands, test mode

🙈 connect / roam / notify — the drama arc

bestie the list literally trails off with a comma after struct cfg80211_beaconing_check_config(9) — it's giving "to be continued" 😭 keep reading, there's more page after this 🫶

...and the see-also roster keeps going, bestie — no cap, it's a whole squad. Every single one, in order, exactly as written:

Like, that's the entire friend group 💖 manifesting in your man pages. Go click through them, iykyk.

And that's a wrap on this one, bestie! 🎀 This lil masterpiece lives in ./include/net, it's stamped October 2026, and the whole thing is filed under ieee80211_data_to_8023(9). Slay, read responsibly, and go touch some grass — or at least go read the next man page. 🦋✨👑
