STRUCT EFX_LINK_STATE(9)

💖 struct efx_link_state(9) 💖

okay so bestie, welcome to the Kernel API Manual glow-up for struct efx_link_state — it's literally the current state of the link, and it's giving main-character energy in the sfc/siena networking universe. 🦋

✨ NAME ✨

struct efx_link_state — current state of the link 👑

🌸 SYNOPSIS 🌸

struct efx_link_state {
    bool up;
    bool fd;
    u8 fc;
    unsigned int speed;
};

🎀 Members 🎀

• up — link is up, yup yup, it's alive and connected 💅
• fd — link is full-duplex, so both directions can talk at once, slay 🫶
• fc — the actual flow control flags, no cap, this is what's really happening with flow control 🌈
• speed — link speed in Mbps, the literal number, periodt ⭐
