💖 phy_is_default_hwtstamp(9) — Kernel API Manual 💖

bestie, welcome to the Kernel API Manual page for phy_is_default_hwtstamp(9) — we are absolutely gonna eat this up ✨

🌸 NAME 🌸

phy_is_default_hwtstamp — Is the PHY hwtstamp the default timestamp

✨ SYNOPSIS ✨

bool phy_is_default_hwtstamp (struct phy_device *phydev );

🎀 ARGUMENTS 🎀

• phydev — Pointer to phy_device 🫶

💅 DESCRIPTION 💅

okay so this function is how you get the default timestamping device, and it fully takes into account the new API choice. The tea: if phydev does not have the default_timestamp flag enabled, then timestamping is selected from the MAC by default. no cap, that’s the whole vibe 😌

🔥 RETURN 🔥

True if the phy is the default hw timestamp, false otherwise. periodt 💖
