STRUCT IWL_SCAN_CHANNEL_PARAMS_V4(9)

💅 struct iwl_scan_channel_params_v4(9) — channel params, but make it cute

Okay so bestie, you're looking at struct iwl_scan_channel_params_v4(9) from the Kernel API Manual 👑 and like... it's genuinely the channel-params struct. That's the whole vibe. It's the version-4 glow-up where the firmware gets told exactly which channels to scan and how long to hang out on each one. No cap ✨

🌸 SYNOPSIS 🌸

Here's the literal shape of her, copy-pasted with love:

struct iwl_scan_channel_params_v4 {
    u8 flags;
    u8 count;
    u8 num_of_aps_override;
    u8 reserved;
    struct iwl_scan_channel_cfg_umac
channel_config[SCAN_MAX_NUM_CHANS_V3];
    u8 adwell_ch_override_bitmap[16];
 };

Like, look at her. Four tiny u8s at the top for the metadata, then a whole array of struct iwl_scan_channel_cfg_umac for the actual channels, then a 16-byte bitmap doing adaptive-dwell things. Main character energy fr fr 🎀

✨ Members ✨ (the whole cast, nobody gets cut)

• flags — the channel flags, and the type is enum iwl_scan_channel_flags. That's it, that's the field 💅
• count — how many channels are in the scan request. Like a guest list count, but for radio channels 🦋
• num_of_aps_override — this one overrides the number of APs the FW (firmware, bestie) uses to calculate dwell time when adaptive dwell is in play. So you're basically saying "hey, count this many APs instead" 🙈
• reserved — for future use and alignment. She's just vibing there, holding space 🫶
• channel_config — an array of explicit channel configurations for the 2.4Ghz and 5.2Ghz bands. Yes, both bands, she's inclusive like that 🌈
• adwell_ch_override_bitmap[16] — okay so when adaptive dwell is on, this bitmap overrides the number of APs value with num_of_aps_override for the channel. And to cast a channel to an index, you use iwl_mvm_scan_ch_and_band_to_idx. That's the iykyk of it 🔥

⚠️ Heads up: reserved literally says "for future use and alignment" — so don't go stuffing your own data in there, bestie. That's not your lane 💀

And that's the page, bestie! Sourced straight from ./drivers/net/wireless/intel/i..., dated October 2026, and she's still signed struct iwl_...el_params_v4(9) at the bottom because legends never change their header. Periodt 💅🎀✨
