STRUCT QLINK_CMD_SCAN(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, welcome to the kernel API manual, and today's main character is qlink_cmd_scan — literally the data for the QLINK_CMD_SCAN command. she's giving "scan request packet" energy and she ate 💖

🌸 NAME 🌸

struct qlink_cmd_scan — the data for the QLINK_CMD_SCAN command. that's it, that's the vibe 🫶

✨ SYNOPSIS ✨

struct qlink_cmd_scan {
    struct qlink_cmd chdr;
    __le64 flags;
    __le16 n_ssids;
    __le16 n_channels;
    __le16 active_dwell;
    __le16 passive_dwell;
    __le16 sample_duration;
    u8 bssid[ETH_ALEN];
    u8 scan_width;
    u8 rsvd[3];
    u8 var_info[];
 };

no cap, that's the whole layout, copy it exactly or the vibe check fails 😭

🦋 Members 🦋

okay so let's go member by member, bestie, because every single one matters 👑

  • flags — the scan flags, and she's a bitmap of enum qlink_scan_flags. iykyk 🔥
  • n_ssids — how many WLAN_EID_SSID TLVs we're expecting in the variable portion of the command. count 'em, don't guess 💅
  • n_channels — how many QTN_TLV_ID_CHANNEL TLVs we're expecting in the variable payload. same energy, different TLV 🌈
  • active_dwell — the time spent on a single channel for an active scan. she dwells, she's thorough ✨
  • passive_dwell — the time spent on a single channel for a passive scan. same but silent, lowkey 🍓
  • sample_duration — the total duration of sampling a single channel during a scan, and yes that includes the off-channel dwell time and the operating channel time. all of it, no crumbs left 🎀
  • bssid — the specific BSSID to scan for, or a broadcast BSSID. be picky or be everyone's type 💖
  • scan_width — the channel width to use, and it's one of enum qlink_channel_width. pick your width, icon 👑

ngl this list is long and it's giving "linked universe", so buckle up bestie 🧚

nerd alert 🎀 the rsvd[3] and var_info[] members show up in the struct itself — the members rundown above covers the ones the page describes, so don't come for me, bestie 🙈

and that's the whole page, periodt 💜 this cutie came out of ./drivers/net/wireless/quanten... and she's dated October 2026 — so yes, she's from the future, main character energy fr fr ⭐👑💅
