ENUM ES58X_PHYSICAL_LAYER(9)

💅 enum es58x_physical_layer(9) — bestie edition

okay so this is a page from the Kernel API Manual, and honestly? it's a short one, but it ate. let's get into it 🫶

---

✨ NAME ✨

enum es58x_physical_layer — literally just: what kind of physical layer are we talking about. that's the whole vibe check 🔥

---

🌸 SYNOPSIS 🌸

enum es58x_physical_layer {
    ES58X_PHYSICAL_LAYER_HIGH_SPEED

};

that's it. that's the whole enum. one (1) member. she's minimal, she's iconic, she's not doing extra credit 💅

---

🎀 Constants 🎀

• ES58X_PHYSICAL_LAYER_HIGH_SPEED — high-speed CAN, c.f. ISO 11898-2. the fast one. the main character ⚡

---

🦋 DESCRIPTION 🦋

so like… some products in the ETAS portfolio do also support low-speed CAN (c.f. ISO 11898-3), which is cool for them, love that for them 💖

buuut — and this is the important part, no cap — all the devices in scope of this driver do not support the option. so the enum has only one member. that's it. that's the reason. one member, zero drama 🧚

ngl this is the most "we checked and there's nothing else to add" enum i've ever seen and i respect it 😭
