STRUCT IWL_RX_HANDLER(9)

🦋 struct iwl_rx_handler(9) 🦋

okay bestie, welcome to the Kernel API Manual ✨ we're talking about struct iwl_rx_handler and honestly? it's giving "handler for FW notification" and it ate 💅

---

🌸 NAME 🌸

struct iwl_rx_handler — the handler for FW notification, no cap 🫶

---

✨ SYNOPSIS ✨

struct iwl_rx_handler {
    union {
      bool (*val_fn)(struct iwl_mld *mld, struct iwl_rx_packet *pkt);
      const struct iwl_notif_struct_size *sizes;
    };
    void (*fn)(struct iwl_mld *mld, struct iwl_rx_packet *pkt);
    u16 cmd_id;
    u8 n_sizes;
    u8 context;
    enum iwl_mld_object_type obj_type;
    bool (*cancel)(struct iwl_mld *mld, struct iwl_rx_packet *pkt, u32
obj_id);
 };

literally the whole vibe is right there 👑 copy it exactly, don't be weird about it 🙈

🎀 Members 🎀

• {unnamed_union} — anonymous, she has no name and she doesn't need one 💅 (an anonymous union, bestie)
• val_fn — the input validation function. she checks your vibe before anything else gets through ⭐
• sizes — an array that maps a version to the expected size 📏 lowkey the lookup table of the group chat
• fn — the function that's called when the notification is handled 🔥 main character energy fr fr
• cmd_id — the command id 🏷️ that's it, that's the whole thing
• n_sizes — how many elements are in sizes 🔢 count her blessings
• context — see iwl_rx_handler_context 🧚 context is everything, iykyk
• obj_type — the type of object this handler is related to, see iwl_mld_object_type 👑 and if it's not related to anything? use IWL_MLD_OBJECT_TYPE_NONE 🫶
• cancel — function to cancel the notification 🚫 valid only if obj_type is not IWL_MLD_OBJECT_TYPE_NONE — like, that's the rule, don't test her 💀

ngl bestie, get the obj_type / cancel situation right or it's giving undefined vibes 😭

that's the whole page, periodt 💖 this cutie came from ./drivers/net/wireless/intel/i... (that's the source/version line) and it's dated October 2026, and the manual is struct iwl_rx_handler(9) — slay, go handle some FW notifications 🦋✨🎀
