register_mii_timestamper(9)

💅 register_mii_timestamper(9) — a Kernel API Manual moment 🎀

Okay bestie, so this is a page from the Kernel API Manual and it's about register_mii_timestamper, and honestly it's short and sweet, so let's get into it ✨

---

🌸 NAME 🌸

register_mii_timestamper — enables a given port of an MII time stamper 💖

Like, that's the whole vibe. It turns a port ON. Slay.

---

🦋 SYNOPSIS 🦋

struct mii_timestamper * register_mii_timestamper (struct device_node
*node , unsigned int port );

That's it, that's the signature, no cap 🫶

---

🎀 ARGUMENTS 🎀

• node — the device tree node of the MII time stamp controller 🌳 like, which controller we're talking about, bestie.
• port — the index of the port to be enabled 🔢 aka which one of its ports you want switched on.

---

⭐ DESCRIPTION ⭐

So what does it actually do? It returns a valid interface on success or ERR_PTR otherwise 💀 That's the whole description. Short king of a description, honestly. But hey — at least you know what you're getting: either a real, valid interface, or an ERR_PTR telling you it didn't work out 😭

👑 SEE ALSO 👑

• Kernel file ./drivers/net/phy/mii_timestamper.c 📁
• register_mii_tstamp_controller(9)
• unregister_mii_tstamp_controller(9)
• unregister_mii_timestamper(9)

iykyk, these are the friends in the same group chat 🫶

ngl bestie, remember: on failure you get ERR_PTR back, not a NULL — so vibe check your return value properly before you dereference anything 💅
