ENUM DPMAC_ETH_IF(9)

✨ NAME ✨

Okay so bestie, gather round 💖 — this is the manual page for enum dpmac_eth_if, and it's lowkey just the DPMAC Ethrnet interface. Yes, "Ethrnet." That's the kernel's typo, not mine, and honestly? We're keeping it, we're not fixing it, we don't do that here 🎀. This is a page from the Kernel API Manual, so you know it's giving serious main-character documentation energy 👑

🦋 SYNOPSIS 🦋

Like, the whole enum in all its glory, verbatim, no cap:

enum dpmac_eth_if {
    DPMAC_ETH_IF_MII ,
    DPMAC_ETH_IF_RMII ,
    DPMAC_ETH_IF_SMII ,
    DPMAC_ETH_IF_GMII ,
    DPMAC_ETH_IF_RGMII ,
    DPMAC_ETH_IF_SGMII ,
    DPMAC_ETH_IF_QSGMII ,
    DPMAC_ETH_IF_XAUI ,
    DPMAC_ETH_IF_XFI ,
    DPMAC_ETH_IF_CAUI ,
    DPMAC_ETH_IF_1000BASEX ,
    DPMAC_ETH_IF_USXGMII

};

Behold. Twelve constants. Not eleven, not thirteen. Twelve. The way this enum ate and left no crumbs 😭🔥

🌸 Constants 🌸

Every single one of these baddies, in order, with zero skipped 💅:

• DPMAC_ETH_IF_MII — this one's the MII interface. Iconic. The OG.
• DPMAC_ETH_IF_RMII — RMII interface. That's the "R" variant, she's here, she's valid 🦋
• DPMAC_ETH_IF_SMII — SMII interface. Yes bestie, all three MII-adjacent girlies showed up ⭐
• DPMAC_ETH_IF_GMII — GMII interface. The G is for gorgeous, ngl (jk it's just GMII, don't come for me 🙈)
• DPMAC_ETH_IF_RGMII — RGMII interface. Sibling of GMII, equally slay ✨
• DPMAC_ETH_IF_SGMII — SGMII interface. Honestly this one is doing the most and we love her 💜
• DPMAC_ETH_IF_QSGMII — QSGMII interface. The Q stands for "queen," obviously 👑
• DPMAC_ETH_IF_XAUI — XAUI interface. X-A-U-I. Say it with your chest 🔥
• DPMAC_ETH_IF_XFI — XFI interface. Short, mysterious, three letters of pure vibe check 💀
• DPMAC_ETH_IF_CAUI — CAUI interface. Right there in the lineup, thriving 🎀
• DPMAC_ETH_IF_1000BASEX — 1000BASEX interface. The only one with digits, and she knows it 💖
• DPMAC_ETH_IF_USXGMII — USXGMII interface. Final girlie of the enum, closing out the list with a bow 🎁

That's it, that's the constants. Every one of them is literally just an "interface" and that is the entire tea ☕

💅 SEE ALSO 💅

Go read the source, bestie, it's right there in the kernel tree:

• Kernel file ./drivers/net/ethernet/freescale/dpaa2/dpmac.h — that's where this enum lives, go stan the header 🫶
• enum dpmac_link_type(9)
• struct dpmac_attr(9)
• struct dpmac_link_state(9)
• enum dpmac_counter_id(9)

The whole friend group fr fr 🌈 — read them all, you'll be a DPMAC expert by the end of the night 😤

No arguments, no options, no exit statuses, no environment variables on this one — just a clean little enum living its best life in a header file. Sometimes that's all you need 🧚💫

Kept for the archives by ./drivers/net/ethernet/freesca..., and yes the date really says October 2026 — she's from the future, and she came back specifically to tell you about ethernet interfaces 💜🦋✨
