phy_has_txtstamp(9)

💅 phy_has_txtstamp(9) 💅

Okay so welcome to the Kernel API Manual, bestie — this is the page for phy_has_txtstamp, and it's lowkey a very focused little icon. ✨

🌸 NAME 🌸

phy_has_txtstamp — tests whether a PHY supports transmit time stamping. That's the whole assignment: a PHY vibe check for transmit time stamping support, and the answer comes back as a bool. No cap. 🫶

✨ SYNOPSIS ✨

bool phy_has_txtstamp (struct phy_device *phydev );

It's giving "one function, one argument, zero drama" — and honestly? Obsessed. 💖

🎀 ARGUMENTS 🎀

• phydev — the phy_device struct. That's the PHY device you're asking about, bestie; hand it over and let the function do its yes/no thing. 🫶
