STRUCT PSE_ADMIN_STATE(9)

✨ struct pse_admin_state(9) ✨

okay so we're in the Kernel API Manual, section 9 bestie, and today's main character is struct pse_admin_state — literally the PSE operational state, no cap 💅

---

🎀 NAME 🎀

struct pse_admin_state — the PSE operational state. that's it, that's the vibe. it's giving "small struct, big responsibility" ✨

---

🌸 SYNOPSIS 🌸

struct pse_admin_state {
    enum ethtool_podl_pse_admin_state podl_admin_state;
    enum ethtool_c33_pse_admin_state c33_admin_state;
 };

like… two members. two. and yet she's iconic 🫶 both of them are enums, both of them are about admin state, and yes you need both, don't @ me.

---

🦋 Members 🦋

• podl_admin_state — the operational state of the PoDL PSE functions, fr fr. she's defined by IEEE 802.3-2018 30.15.1.1.2 aPoDLPSEAdminState — yes that's a real citation, write it down 📝
• c33_admin_state — the operational state of the PSE functions (the C33 flavor, iykyk). this one comes from IEEE 802.3-2022 30.9.1.1.2 aPSEAdminState 💖

bestie pls don't mix them up — one is the PoDL PSE functions and the other is the PSE functions, and they cite two different IEEE specs (2018 vs 2022, okurrr). the struct does not merge them and neither should you 🙈

so yeah — that's the whole struct, bestie. go forth and check your admin states. periodt 💜
