STRUCT ETHTOOL_PHY_STATS(9)

💅 struct ethtool_phy_stats(9) 💅

okay bestie, this is the struct ethtool_phy_stats(9) page from the Kernel API Manual, and it's literally all about PHY-level stats counters. no cap, let's get into it 🫶

---

✨ NAME ✨

struct ethtool_phy_stats — PHY-level statistics counters

---

🎀 SYNOPSIS 🎀

here's the whole struct vibe, copy-paste exact:

struct ethtool_phy_stats {
    u64 rx_packets;
    u64 rx_bytes;
    u64 rx_errors;
    u64 tx_packets;
    u64 tx_bytes;
    u64 tx_errors;
 };

---

🌸 Members 🌸

• rx_packets — total successfully received frames ✨
• rx_bytes — total successfully received bytes 💖
• rx_errors — total received frames with errors (like, e.g., CRC errors — classic 💀)
• tx_packets — total successfully transmitted frames 🦋
• tx_bytes — total successfully transmitted bytes 🌈
• tx_errors — total transmitted frames with errors 🙈

---

💫 Description 💫

so this structure is the standardized interface for reporting PHY-level statistics counters. that's the whole main character energy of it.

it's designed to expose stats that PHYs commonly provide but that are not explicitly defined in the IEEE 802.3 standard. iykyk — it's giving "we made a struct for the stuff the spec forgot" 💅
