STRUCT PHY_C45_DEVICE_IDS(9)

🦋 struct phy_c45_device_ids(9) 🦋

okay bestie, this page comes from the Kernel API Manual, and it's all about struct phy_c45_device_ids — the 802.3-c45 Device Identifiers vibe. no cap, it's a tiny struct with main-character energy, and we're gonna go through every single field together 🫶

🌸 NAME 🌸

struct phy_c45_device_ids — 802.3-c45 Device Identifiers. literally the name says it all, periodt 💅

✨ SYNOPSIS ✨

       struct phy_c45_device_ids {
           u32 devices_in_package;
           u32 mmds_present;
           u32 device_ids[MDIO_MMD_NUM];
        };

🎀 Members 🎀

• devices_in_package — the IEEE 802.3 devices in package register value. yep, that's the register value, bestie, exactly what it says 🍓
• mmds_present — a bit vector of MMDs present. bit vector, not a vibe vector (though it is giving bit vector energy) ✨
• device_ids — the device identifier for each present device. one ID per present device, slay 💖
