STRUCT DPNI_LINK_STATE(9)

💅 struct dpni_link_state(9)

Okay so bestie, welcome to the Kernel API Manual — yes, that kernel API manual — and today's main character is struct dpni_link_state. It's the struct that literally represents your DPNI link state. Three fields. Zero filler. We love a minimalist icon. 🎀

---

✨ NAME ✨

struct dpni_link_state — Structure representing DPNI link state. That's the whole description and honestly? It ate. No notes. 🌸

---

🦋 SYNOPSIS 🦋

struct dpni_link_state {
    u32 rate;
    u64 options;
    int up;
 };

Look at her. Gorgeous. Note the types, bestie — u32, u64, and a plain int — copy them exactly because the compiler is not forgiving and will not be doing a vibe check before it yells at you. 😭

🧚 Members 🧚

• rate — Rate. That's it, that's the description. u32. The docs said what they said and nothing more. 💀
• options — Mask of available options; use 'DPNI_LINK_OPT_<X>' values. It's a u64, so there's plenty of room in there for every option you're about to pile on. 🔥
• up — Link state; '0' for down, '1' for up. Binary queen. No in-between, no "it's complicated", just 0 or 1. 👑
