stmmac_hwtstamp_get(9)

💅 stmmac_hwtstamp_get 💅

Okay bestie, so this is a page from the Kernel API Manual — yes, that manual, section 9, the kernel-internals one — and it's all about one lil function called stmmac_hwtstamp_get. She's a getter. She reads. That's her whole thing and honestly? Iconic. 🎀

---

✨ NAME ✨

stmmac_hwtstamp_get — read hardware timestamping. That's it, that's the vibe check: she reads the hardware timestamping situation. 👑

---

🌸 SYNOPSIS 🌸

int stmmac_hwtstamp_get (struct net_device *dev , struct
       kernel_hwtstamp_config *config );

She returns an int, she takes two things, no cap. 🫶

---

🦋 ARGUMENTS 🦋

• dev — device pointer, aka the network device in question. She needs to know which device we're talking about, obviously. 🙈
• config — the timestamping configuration. This is the struct that's gonna hold the goods — struct kernel_hwtstamp_config, to be exact. 💖

---

💜 DESCRIPTION 💜

So like, this function obtains the current hardware timestamping settings — as requested. That's the whole assignment, and she ate. 🍓

Lowkey the most important word here is current — she's reading what's actually set right now, not imagining anything. Read-only energy, main character behavior, periodt. ✨

Alright bestie, that's the page! 🧚 Sourced from the wilds of ./drivers/net/ethernet/stmicro..., dated October 2026, and yes, it's still titled stmmac_hwtstamp_get(9) at the bottom like a little name tag at the end of the party. Go get those timestamps, queen. 👑💖
