💅 mii_resolve_flowctrl_fdx 💅

Okay so bestie, we're in the mii_resolve_flowctrl_fdx(9) zone — that's the page name, and it's from the Kernel API Manual, in case the vibe check needed a label. Strap in, this one's short but it's iconic in a very specific nerdy way. 🧚

✨ NAME ✨

mii_resolve_flowctrl_fdx — and ngl, the description is literally blank in the original, no cap. The name is the whole personality here. 💀

---

🌸 SYNOPSIS 🌸

u8 mii_resolve_flowctrl_fdx (u16 lcladv , u16 rmtadv );

It takes two u16s, gives you back a u8. That's the whole shape of it, bestie. 🫶

---

🎀 ARGUMENTS 🎀

• lcladv — the value of the MII ADVERTISE register. That's your side's advertisement, your little card you're putting out there. 💌
• rmtadv — the value of the MII LPA register. That's the remote link partner's word back to you. 📬

---

💖 DESCRIPTION 💖

So what does it actually do? It resolves full duplex flow control as per IEEE 802.3-2005 table 28B-3. Like, that specific table. Not a vibe-based guess, an actual spec table. Slay. ✨

Lowkey a reminder: the original page literally has no prose under NAME and nothing but the spec reference under DESCRIPTION. That's not me skipping the boring parts — that's the entire page. Fr fr. 🙈

And that's the tea, bestie 🌈 — this page is from the Kernel API Manual, dated October 2026, and it comes to you straight from ./include/linux. Go forth and resolve some flow control. Periodt. 💅👑
