💅 ethtool_get_ts_info_by_layer(9) 💅

okay so bestie, welcome to the Kernel API Manual ✨ — yes, that's the manual name, and yes, this page is genuinely about one function that tells you whether your timestamping magic lives in the MAC layer or the PHY layer. no cap, it's giving niche-but-iconic 🎀

---

🌸 NAME 🌸

ethtool_get_ts_info_by_layer — Obtains time stamping capabilities from the MAC or PHY layer. 🕰️✨

---

🦋 SYNOPSIS 🦋

int ethtool_get_ts_info_by_layer (struct net_device *dev , struct kernel_ethtool_ts_info *info );

---

💖 ARGUMENTS 💖

• dev — pointer to net_device structure. it's the netdev you're asking about, the main character of this whole operation 👑
• info — buffer to hold the result. this is where the answer lands, so like… make sure it's valid, bestie 💅

---

✨ RETURN ✨

zero on success, non-zero otherwise. literally that's it. zero = slay, non-zero = something's off 😭
