STRUCT QLINK_CHANNEL(9)

okay so bestie, this is struct qlink_channel(9) from the Kernel API Manual, and it is literally the qlink control channel definition. Buckle up, it's giving kernel wireless lore but make it cute 💖

💖 NAME 💖

struct qlink_channel — qlink control channel definition. That's the name, that's the vibe, periodt.

✨ SYNOPSIS ✨

Here's the exact struct, no touchy:

       struct qlink_channel {
           __le16 hw_value;
           __le16 center_freq;
           __le32 flags;
           u8 band;
           u8 max_antenna_gain;
           u8 max_power;
           u8 max_reg_power;
           __le32 dfs_cac_ms;
           u8 dfs_state;
           u8 beacon_found;
           u8 rsvd[2];
        };

🌸 Members 🌸

• hw_value — hardware-specific value for the channel ✨
• center_freq — center frequency in MHz 📡
• flags — channel flags from enum qlink_channel_flags 🚩
• band — band this channel belongs to 🎀
• max_antenna_gain — maximum antenna gain in dBi 📶
• max_power — maximum transmission power (in dBm) 🔥
• max_reg_power — maximum regulatory transmission power (in dBm) 👑
• dfs_state — current state of this channel. Only relevant if radar is required on this channel. 🫶
• beacon_found — helper to regulatory code to indicate when a beacon has been found on this channel. Use regulatory_hint_found_beacon to enable this — it's useful only on the 5 GHz band. 🌈

Tiny side note: the struct above also has __le32 dfs_cac_ms and u8 rsvd[2], but the Members list on this page doesn't give them individual blurbs, so I'm not inventing any. 💀
