STRUCT IWL_SCAN_CHANNEL_PARAMS_V8(9)

🌸 struct iwl_scan_channel_params_v8 💅

okay bestie, welcome to the Kernel API Manual — yes it's a real manual, yes it's about the Linux kernel, and yes you're gonna understand it. this page is all about struct iwl_scan_channel_params_v8, and honestly? it's giving channel params. that's literally the whole vibe. 🦋

---

✨ NAME ✨

struct iwl_scan_channel_params_v8 — channel params. that's it, that's the name, no notes. 🎀

---

🔥 SYNOPSIS 🔥

here's the shape of the thing, copied exactly so nobody comes for me:

struct iwl_scan_channel_params_v8 {
    u8 flags;
    u8 count;
    u8 n_aps_override[2];
    struct iwl_scan_channel_cfg_umac
channel_config[SCAN_MAX_NUM_CHANS_V4];
 };

not me noticing that channel_config line breaks right after the type name — that's just how it's written, don't @ me, I'm not touching it. 💀

💖 MEMBERS 💖

each field, one by one, main character energy:

• flags — channel flags, and the type is enum iwl_scan_channel_flags. iconic little bitfield moment. ⭐
• count — num of channels in scan request. yes, exactly what it sounds like: how many channels you're asking about. 🔢
• n_aps_override — ngl this one's the spicy one 🌶️. it overrides the number of APs the FW uses to calculate dwell time when adaptive dwell is used. here's the tea: channel k will use n_aps_override[i] when BIT(20 + i) is set in channel_config[k].flags. so the index into n_aps_override is decided by those bits in the matching channel's flags. iykyk. 🧚
• channel_config — array of explicit channel configurations for 2.4Ghz and 5.2Ghz bands. it's declared as struct iwl_scan_channel_cfg_umac channel_config[SCAN_MAX_NUM_CHANS_V4]; so like, one entry per channel, and there's a max (SCAN_MAX_NUM_CHANS_V4, we love a named constant 👑). 🌈

heads up bestie: this page is docs only — no behavior guarantees hiding in here beyond what's written above. if you need the actual definitions, go read the header (./drivers/net/wireless/intel/iwlwifi/fw/api/scan.h), not my vibes. 🙈

and that's the whole page!! 🫶 shoutout to the source, ./drivers/net/wireless/intel/i..., dated October 2026, still out here shipping struct iwl_scan_channel_params_v8(9) documentation. slay. 🎀✨
