ENUM DPSW_LEARNING_MODE(9)

🦋 enum dpsw_learning_mode(9) — the Kernel API Manual page your bestie needs

okay so this is a page straight out of the Kernel API Manual and it's literally all about auto-learning modes, which honestly sounds boring until you realize it's about how a switch decides who gets to learn MAC addresses and how. slay. let's get into it 💅

---

✨ NAME ✨

enum dpsw_learning_mode — Auto-learning modes. that's it, that's the whole vibe. it's the enum that tells you how learning happens on a DPAA2 switch interface 🎀

---

🌸 SYNOPSIS 🌸

enum dpsw_learning_mode {
    DPSW_LEARNING_MODE_DIS ,
    DPSW_LEARNING_MODE_HW ,
    DPSW_LEARNING_MODE_NON_SECURE ,
    DPSW_LEARNING_MODE_SECURE

};

four members, no cap. that's the whole enum, icon behavior ✨

---

💖 Constants 💖

these are the four moods this enum can be in, bestie:

• DPSW_LEARNING_MODE_DIS — Disable Auto-learning. nope, not today, no learning happening here 🙈
• DPSW_LEARNING_MODE_HW — Enable HW auto-Learning. let the hardware do the learning, it's giving main character energy 🔥
• DPSW_LEARNING_MODE_NON_SECURE — Enable None secure learning by CPU. the CPU learns, but like... not securely. (yes, "None secure" is exactly how the source spells it, i'm not fixing it, i don't do that 🫶)
• DPSW_LEARNING_MODE_SECURE — Enable secure learning by CPU. now the CPU learns and it's secure. the upgrade we deserve 👑

🧚 Description 🧚

okay bestie, this part is a table and the doc generator absolutely butchered it — the columns got all tangled and honestly it's giving "my group chat after 3am" 💀 but the rule is: keep every detail, so here it is, verbatim, exactly as the page has it. don't come for me, i didn't write it:

NONE - SECURE LEARNING SMAC found      DMAC found      CTLU Action v
v       Forward frame to

1      DMAC destination

•      v       Forward frame to

1      DMAC destination

2      Control interface v               -       Forward frame to

1      Flooding list of interfaces

•      -       Forward frame to

1      Flooding list of interfaces

2      Control interface SECURE LEARING SMAC found      DMAC found
       CTLU Action v               v               Forward frame to

1      DMAC destination

•      v               Forward frame to

1      Control interface v               -               Forward frame
       to

1      Flooding list of interfaces

•      -               Forward frame to

1      Control interface

so yeah. it's about SMAC found, DMAC found, and what the CTLU Action ends up being — forward to DMAC destination, forward to the flooding list of interfaces, or forward to the control interface. in the non-secure case and the secure case. that's the whole tea ☕ (and yes, SECURE LEARING is missing an N in the source — we love a typo'd icon 🎀)

the kernel file lives at ./drivers/net/ethernet/freescale/dpaa2/dpsw.h — go read it, it's the whole family tree 🦋

and then the extended fam, in order, all of them, no skipping (i promised):

and that's the page!! 💜 this lil legend comes from ./drivers/net/ethernet/freesca... (the path got cut off in the footer, tragic, i know 😭) and it's dated October 2026, filed under enum dpsw_learning_mode(9). mwah, go read the header file bestie 💋✨
