__phy_hwtstamp_set(9)

💖 NAME 💖

okay so this page is from the Kernel API Manual, section (9), and it's about __phy_hwtstamp_set — the little function that modifies PHY hardware timestamping configuration ✨🕰️

✨ SYNOPSIS ✨

int __phy_hwtstamp_set (struct phy_device *phydev , struct kernel_hwtstamp_config *config , struct netlink_ext_ack *extack );

🎀 ARGUMENTS 🎀

• phydev — the PHY device structure, aka the actual star of the show, the device whose vibes we're adjusting 🌸
• config — the structure holding the timestamping configuration, like the outfit the timestamping is gonna wear 👑
• extack — the netlink extended ack structure, which exists so errors get reported back properly (no silent ghosting here, bestie) 😭

🦋 SEE ALSO 🦋

it lives in the kernel file ./drivers/net/phy/phy.c, and like... it has so many neighbors, ngl. whole little ecosystem 💅

go read them all, i'll wait. jk jk... unless? 👀

and that's the whole page, bestie!! this one came from ./drivers/net/phy and it's dated October 2026 — like, future energy fr fr 💀⏰ slay, see u in the next manpage 💜🧚
