STRUCT HWSIM_TX_RATE(9)

🦋 struct hwsim_tx_rate(9) 🦋

okay bestie, welcome to the Kernel API Manual — this one is literally all about struct hwsim_tx_rate and it's giving rate-selection realness ✨

---

🌸 NAME 🌸

struct hwsim_tx_rate — rate selection/status, periodt 💅

---

✨ SYNOPSIS ✨

the whole struct is right here, no cap:

       struct hwsim_tx_rate {
           s8 idx;
           u8 count;
        };

---

🎀 Members 🎀

• idx — the rate index you're gonna attempt to send with 👑
• count — how many tries happen in this rate before moving on to the next rate 🔁

---

💖 Description 💖

so like, a value of -1 for idx means invalid rate 🚨 and if that shows up in an array of retry rates, it means no more rates should be tried — full stop, bestie.

when this is used for transmit status reporting, the driver should always report the rate and the number of retries used. always always. no skipping 🙈
