STRUCT EF4_LINK_STATE(9)

🦋 NAME 🦋

struct ef4_link_state — the current state of the link, literally that's it, that's the whole thing 💖

✨ SYNOPSIS ✨

okay so welcome to the Kernel API Manual, bestie — here's the whole struct, no cap, exactly as it is:

struct ef4_link_state {
    bool up;
    bool fd;
    u8 fc;
    unsigned int speed;
 };

🌸 Members 🌸

the little squad living inside this struct, one by one 🫶

• up — the link is up. that's it. that's the field. it's a whole bool about whether the link is up 💅
• fd — the link is full-duplex. both directions at the same time, we love a two-way situation ✨
• fc — the actual flow control flags. actual. not the pretend ones. the real ones 🔥
• speed — the link speed, in Mbps. Mbps, not MB/s, don't come for me 😭
