okay so bestie, welcome to the Kernel API Manual — yes this page's title is literally abbreviated with dots in the middle, that's just how it is, we don't question the kernel's naming choices, we simply vibe with them 🫶

✨ NAME ✨

mmd_eee_cap_to_ethtool_sup_t — no cap, that's the whole name, and yes it's a mouthful, iykyk 😭

---

🌸 SYNOPSIS 🌸

u32 mmd_eee_cap_to_ethtool_sup_t (u16 eee_cap );

that's it, that's the whole signature, she's short and she's iconic 💖

---

🎀 ARGUMENTS 🎀

• eee_cap — the value of the MMD EEE Capability register. that's the input, that's what you're handing over, that's the whole assignment bestie 🦋

---

💅 DESCRIPTION 💅

so what does she do? literally just this: mmd_eee_cap_to_ethtool_sup_t is a small helper function that translates the bits from the MMD EEE Capability register — that's register 3.20, fyi, super specific — into ethtool supported settings. that's the whole job. translating bits. one direction. no drama. she ate and left no crumbs ✨

like, it's giving "tiny little translator fairy" 🧚 — you give her the MMD EEE Capability (3.20) bits, she gives you back the ethtool supported settings, and everyone moves on with their day. lowkey obsessed with how clean that is 💜
