STRUCT ATH5K_TXQ(9)

💅 struct ath5k_txq(9) — Transmit queue state 💅

okay bestie, this is the Kernel API Manual entry for struct ath5k_txq, aka Transmit queue state — and honestly? The way this struct is just sitting here managing queue lore is iconic ✨💖

🌸 NAME 🌸

struct ath5k_txq — Transmit queue state 🎀

---

🦋 SYNOPSIS 🦋

       struct ath5k_txq {
           unsigned int            qnum;
           u32 *link;
           struct list_head        q;
           spinlock_t lock;
           bool setup;
           int txq_len;
           int txq_max;
           bool txq_poll_mark;
           unsigned int            txq_stuck;
        };

🎀 Members 🎀

• qnum — Hardware q number 👑
• link — Link ptr in last TX desc 🔗
• q — Transmit queue (struct list_head) 🧚
• lock — Lock on q and link 🔒
• setup — Is the queue configured 👀
• txq_len — Number of queued buffers 🍓
• txq_max — Max allowed num of queued buffers 🌈
• txq_poll_mark — Used to check if queue got stuck 💀
• txq_stuck — Queue stuck counter 😭

---

✨ Description ✨

okay so picture this: one of these exists for each hardware transmit queue 🎀. Packets sent to us from above are assigned to queues based on their priority — that's just the system, no cap. Not all devices support a complete set of hardware transmit queues, and for those devices the array sc_ac2q will map multiple priorities to fewer hardware queues (typically all to one hardware queue). That's the whole vibe, fr fr 💅
