STRUCT IWL_SCAN_PROBE_PARAMS_V4(9)

✨ struct iwl_scan_probe_params_v4 — scan probe parameters ✨

okay so bestie, welcome to the struct iwl_scan_probe_params_v4(9) page 💅 this lives in the Kernel API Manual, and it's literally the little bundle of "hey bestie, who are we probing for?" that a scan probe carries around. she's a v4, she's iconic, she's got arrays. let's get into it 🫶

---

🌸 SYNOPSIS 🌸

like, here's her whole lewk, exactly as she is, no notes:

struct iwl_scan_probe_params_v4 {
    struct iwl_scan_probe_req preq;
    u8 short_ssid_num;
    u8 bssid_num;
    __le16 reserved;
    struct iwl_ssid_ie direct_scan[PROBE_OPTION_MAX];
    __le32 short_ssid[SCAN_SHORT_SSID_MAX_SIZE];
    u8 bssid_array[SCAN_BSSID_MAX_SIZE][ETH_ALEN];
};

no cap, that's the whole vibe check ✨

---

🎀 Members 🎀

okay so every single field, and what she actually does — not me skipping any of them, bestie, we're doing all seven 💖

• preq — the scan probe request params themselves. the main character of the whole struct, honestly 👑
• short_ssid_num — how many of the short SSIDs in the short ssid array are actually valid. like, the count of the real ones, not the empties 🙈
• bssid_num — how many BSSIDs in the bssids array are actually valid. same energy, different array 💅
• reserved — reserved. she's just sitting there holding space, we don't touch her 🧘
• direct_scan — list of ssids 🦋
• short_ssid — array of short ssids 🍓
• bssid_array — array of bssids 🌈

fr fr, don't go reading past short_ssid_num in short_ssid or past bssid_num in bssid_array — the counts are the whole point of the counts, iykyk 😭
