STRUCT AFX_HDL(9)

🌸 struct afx_hdl — action frame off channel storage 🌸

ok so this is straight out of the Kernel API Manual (struct afx_hdl(9) section, section 9, kernel docs bestie 💅) and it's literally the lil storage blob for action frame off channel stuff. yes that's a lot of words. stay with me 🫶

✨ NAME ✨

struct afx_hdl — action frame off channel storage.

like, the whole personality is right there in the name. it holds things. it stores things. action frames, off channel. iconic behavior honestly 👑

---

✨ SYNOPSIS ✨

struct afx_hdl {
    struct work_struct afx_work;
    struct completion act_frm_scan;
    bool is_active;
    s32 peer_chan;
    bool is_listen;
    u16 my_listen_chan;
    u16 peer_listen_chan;
    u8 tx_dst_addr[ETH_ALEN];
 };

no cap, that's the whole struct. every field, character for character, don't @ me 😤

✨ MEMBERS ✨

okay now the good part, let's meet the cast 🎀

• afx_work — the worker thread for searching channel 🔍 this is the little guy doing the actual searching, main character energy ngl
• act_frm_scan — thread synchronizing struct. it's the vibes coordinator 🌈 keeps the threads in sync fr fr
• is_active — channel searching active. a bool, so it's very much a yes/no girlie 💖
• peer_chan — current channel. an s32 holding whatever channel we're on rn 📡
• is_listen — sets mode for afx worker. another bool lowkey just flipping the worker's whole mode 👀
• my_listen_chan — this peers listen channel. a u16, and yes the grammar is exactly as the original says it, I'm not touching it 🙈
• peer_listen_chan — remote peers listen channel. also u16, the other side of the story 🦋
• tx_dst_addr — mac address where tx af should be sent to. Type is u8 tx_dst_addr[ETH_ALEN], so it's a whole MAC address array, not a single byte, don't get it twisted ⭐

heads up bestie: peer_chan is s32 but the listen channels are u16 and tx_dst_addr is u8[ETH_ALEN] — the types are NOT interchangeable, keep them exactly as written 💀

and that's the whole page, no notes 💅

sign-off era: this came from ./drivers/net/wireless/broadco... (yes the page really does truncate the path like that, we love a mysterious queen) and it's dated October 2026 — so go forth, search some channels, sync some threads, and slay ✨🎀🔥
