STRUCT QLINK_CHAN_STATS(9)

💅 struct qlink_chan_stats(9) — like, the whole kernel API manual moment

okay so bestie, welcome to the glow-up of struct qlink_chan_stats(9) from the Kernel API Manual ✨. She's a little struct, she lives in the kernel, and she's about to tell you everything about per-channel stats. no gatekeeping here 🫶

---

✨ NAME ✨

struct qlink_chan_stats — the data for QTN_TLV_ID_CHANNEL_STATS 👑

🎀 SYNOPSIS 🎀

struct qlink_chan_stats {
    __le64 time_on;
    __le64 time_tx;
    __le64 time_rx;
    __le64 cca_busy;
    __le64 cca_busy_ext;
    __le64 time_scan;
    s8 chan_noise;
    u8 rsvd[3];
 };

like, that's the whole vibe up there ⬆️ copy it exactly, don't come for me about the spacing 💀

🌸 Members 🌸

bestie these are the fields, and yes every single one matters:

• time_on — how much time the radio was, like, actually operating on that channel ⏱️
• time_tx — how much time the radio spent transmitting on the channel, main character energy fr fr 🔥
• time_rx — how much time the radio spent receiving on the channel, she's listeninggg 👂
• cca_busy — how much time the primary channel was busy 😭
• cca_busy_ext — how much time the secondary channel was busy (yes there's a second one, keep up 💅)
• time_scan — how much radio time went into scanning on the channel 🦋
• chan_noise — the channel noise, ngl she's a little noisy 🙈

💜 Description 💜

So this struct carries per-channel statistics. That's the whole gig ✨.

But — and this is the important part, don't skip it — not all fields may be filled with valid values 🚨. Like, some of them might just be sitting there being useless, no cap. The ones that are valid get called out as valid using a bitmap of enum qlink_chan_stat 👑. And that bitmap? It's carried separately, in a payload of QTN_TLV_ID_BITMAP. so don't go looking for it in here, she's travelling light 🧚
