STRUCT RTL8365MB_CPU(9)

🌸 NAME 🌸

struct rtl8365mb_cpu — the CPU port configuration, bestie 💅 (and yes this is from the Kernel API Manual, we're fancy like that ✨)

---

✨ SYNOPSIS ✨

okay so here's the whole vibe of the struct, look at her go 👑

struct rtl8365mb_cpu {
    bool enable;
    u32 mask;
    u32 trap_port;
    enum rtl8365mb_cpu_insert insert;
    enum rtl8365mb_cpu_position position;
    enum rtl8365mb_cpu_rxlen rx_length;
    enum rtl8365mb_cpu_format format;
 };

🎀 Members 🎀

bestie these are her fields, every single one, no skips 🫶

• enable — turns hardware insertion of the CPU tag in switch->CPU frames on and off. like a lil light switch 💡
• mask — the port mask of the ports that parse should parse CPU tags. yes, that's literally what it says, "parse should parse", she's iconic 💀
• trap_port — the port that trapped frames get forwarded to. catch them 🥅
• insert — the CPU tag insertion mode in switch->CPU frames 🧚
• position — where the CPU tag sits in the frame. location location location 📍
• rx_length — the minimum CPU RX length 📏
• format — the CPU tag format ⭐

🦋 Description 🦋

So basically this struct represents the CPU tagging and CPU port configuration of the switch, periodt. The good news? These settings are configurable at runtime, no reboot-and-pray required 🔥
