ENUM DPNI_CONGESTION_UNIT(9)

💅 NAME 💅

okay so bestie, let me introduce you to enum dpni_congestion_unit — the DPNI congestion units. that's it, that's the whole name. iconic little enum. ✨

---

🦋 SYNOPSIS 🦋

enum dpni_congestion_unit {
    DPNI_CONGESTION_UNIT_BYTES ,
    DPNI_CONGESTION_UNIT_FRAMES

};

no cap, that's literally the whole thing. two members, zero drama. 🌸

---

🎀 Constants 🎀

so these are the two constants living in this enum and they're lowkey the whole personality of the page:

• DPNI_CONGESTION_UNIT_BYTES — bytes units 💖 like, we're counting congestion in bytes, periodt.
• DPNI_CONGESTION_UNIT_FRAMES — frames units 🫶 same vibe check, except we're counting frames instead. choices, bestie, we love a choice.

like… the way this page links to everything 😭 go read them, bestie, they're all right there. iykyk 💀

ngl this one's a short one — it's giving "small but mighty" 💅 no warnings, no flags, no exit statuses, just two units and a truly unhinged amount of cross-references. slay.

anyway that's the whole page, mwah 💜 this lil' writeup came from the Kernel API Manual, section 9, sourced from ./drivers/net/ethernet/freesca..., dated October 2026 — go off, you absolute icon 🎀✨
