ENUM DPSW_STP_STATE(9)

💅 enum dpsw_stp_state(9) — the STP state enum, explained

okay bestie so this page is from the Kernel API Manual, and it's all about enum dpsw_stp_state — like, the Spanning Tree Protocol (STP) states. yes that's the thing that stops your switches from making a loop and having a whole meltdown 😭 it's giving "network self-care" fr fr.

---

✨ SYNOPSIS ✨

here's the whole enum, exactly as it lives, no notes:

enum dpsw_stp_state {
    DPSW_STP_STATE_DISABLED ,
    DPSW_STP_STATE_LISTENING ,
    DPSW_STP_STATE_LEARNING ,
    DPSW_STP_STATE_FORWARDING ,
    DPSW_STP_STATE_BLOCKING

};

like… five states, one enum, main character energy 👑

🎀 Constants 🎀

these are the members, and ngl the names are lowkey self-explanatory, but let's go through them anyway because that's the assignment 💖

• DPSW_STP_STATE_DISABLED — the Disabled state. it's not doing STP things, it's on do-not-disturb 🦋
• DPSW_STP_STATE_LISTENING — the Listening state. it's listening, bestie, it's in its "just vibing and taking it all in" era 🌸
• DPSW_STP_STATE_LEARNING — the Learning state. gathering info, being a little student, iconic 🎀
• DPSW_STP_STATE_FORWARDING — the Forwarding state. it's forwarding, it's slaying, traffic is moving 🔥
• DPSW_STP_STATE_BLOCKING — the Blocking state. blocking, but like, in the STP way — not the petty way 💀

🌸 okay that's the page!! it's from ./drivers/net/ethernet/freesca... and the date on it is October 2026 — yes, the future, she's ahead of her time ⭐ and the footer says enum dpsw_stp_state(9), which is literally just the page coming back to say hi again on its way out. periodt. 💅✨
