STRUCT KSZ_PORT_INFO(9)

💅 struct ksz_port_info(9) 💅

okay bestie, this is the Kernel API Manual page for struct ksz_port_info(9), and it’s giving tiny-struct-big-switch energy. The way that this thing just holds port info? obsessed. No cap.

💖 NAME 💖

struct ksz_port_info — port information data structure. Literally the struct that holds port info, periodt.

✨ SYNOPSIS ✨

struct ksz_port_info {
    uint state;
    uint tx_rate;
    u8 duplex;
    u8 advertised;
    u8 partner;
    u8 port_id;
    void *pdev;
};

• state — connection status of the port. Vibe check for the port, basically.
• tx_rate — transmit rate divided by 10000 to get Mbit. Do the math, bestie.
• duplex — duplex mode. That’s it, that’s the field.
• advertised — advertised auto-negotiation setting. Used to determine link. Lowkey important for link vibes.
• partner — auto-negotiation partner setting. Used to determine link. Also part of the link determination squad.
• port_id — port index to access actual hardware register. Your little index into the actual hardware register.
• pdev — pointer to OS dependent network device. Pointer energy, fr fr.
