STRUCT IWL_SCAN_CONFIG_V1(9)

💖 struct iwl_scan_config_v1(9) 💖

okay bestie, welcome to the Kernel API Manual page for struct iwl_scan_config_v1 — it's the scan configuration command, and we're gonna get into it ✨

---

🎀 NAME 🎀

struct iwl_scan_config_v1 — the scan configuration command, no cap. it literally configures your scans 💅

---

✨ SYNOPSIS ✨

here's the whole glow-up, laid out exactly like the kernel wrote it:

struct iwl_scan_config_v1 {
    __le32 flags;
    __le32 tx_chains;
    __le32 rx_chains;
    __le32 legacy_rates;
    __le32 out_of_channel_time;
    __le32 suspend_time;
    struct iwl_scan_dwell dwell;
    u8 mac_addr[ETH_ALEN];
    u8 bcast_sta_id;
    u8 channel_flags;
    u8 channel_array[];
 };

look at those fields, they're giving organized 😭🫶

---

🌸 Members 🌸

okay so, member by member, we go:

• flags — this one holds enum scan_config_flags. the vibe-check bits of the whole config 🦋
• tx_chains — valid_tx antenna, using the ANT_* definitions. transmission realness 💜
• rx_chains — valid_rx antenna, also ANT_* definitions. receiving, but make it iconic 👑
• legacy_rates — the default legacy rates, typed as enum scan_config_rates. old school but still slaying ⭐
• out_of_channel_time — default max out of serving channel time, in case you were wondering how long we can be away from home 🏠
• suspend_time — default max suspend time. nap time limits, fr fr 😴
• dwell — the dwells for the scan, a whole struct iwl_scan_dwell. that's the "how long do we linger" energy 🧚
• mac_addr — default mac address to be used in probes, sized ETH_ALEN. this is the identity she brings to the party 🎀
• bcast_sta_id — the index of the station in the fw. broadcast station, main character energy 🌈
• channel_flags — default channel flags, enum iwl_channel_flags and scan_config_channel_flag. all the little channel details 🔥
• channel_array — default supported channels. the actual list, flexible size and all, u8 channel_array[] 💫

ngl the channel_array[] is a flexible array member, so she's doing the "trailing data" thing — that's just what the [] means, bestie, no extra lore needed 💅
