STRUCT RX_CTL_MACH(9)

✨ struct rx_ctl_mach(9) ✨

okay so bestie, welcome to the struct rx_ctl_mach page — it's a Kernel API Manual entry and honestly it's giving "tiny struct, big responsibilities" 💅 it lives in the kernel API manual section 9, iykyk.

💖 NAME 💖

struct rx_ctl_mach — the rx activities record 🎀 literally just a little receipt of what the rx side has been up to.

---

🦋 SYNOPSIS 🦋

struct rx_ctl_mach {
    u16 status_err_counter;
    u16 large_err_counter;
    u16 rx_err_counter;
    u16 tx_err_counter;
    u16 fifo_rst_counter;
 };

five u16 counters, no cap, all vibes 🌸 every single one of them is a counter and every single one of them matters, so let's meet the cast 🫶

👑 Members 👑

• status_err_counter — the rx status error counter 🩷 counts up when the rx status goes sideways.
• large_err_counter — the rx get large packet length error counter 😭 for when we try to grab a large packet's length and it just… doesn't go well.
• rx_err_counter — the receive packet error counter 📥 errors on the receiving end, counted with love.
• tx_err_counter — the transmit packet error counter 📤 same energy, but for transmit.
• fifo_rst_counter — the reset operation counter 🔄 every reset operation gets a little tally mark.

💜 Description 💜

so what's the point of all this? to keep track for the driver operation statistics ⭐ that's it, that's the whole job — the driver wants its stats, and this struct is the main character holding them 📊💫
