mii_eee_cap1_mod_linkmode_t(9)

💅 mii_eee_cap1_mod_linkmode_t(9) — the kernel API manual, bestie edition

okay so picture this: you're deep in the kernel networking mines, snooping on a manual name situation, and the function you've stumbled into is mii_eee_cap1_mod_linkmode_t. Say it with me. Iconic. Anyway this is a function from the kernel API manual and I'm gonna walk you through it like we're texting at 2am 🫶

✨ NAME ✨

mii_eee_cap1_mod_linkmode_t — that's the whole name section, no cap, the original literally just gives you the function name and dips 💀 (the manpage header vibes confirm it's the kernel API manual, so jot that down)

---

🌸 SYNOPSIS 🌸

void mii_eee_cap1_mod_linkmode_t (unsigned long *adv , u32 val );

literally the whole signature. void return, two args, exactly as written. don't @ me, that's the source 🎀

---

🦋 ARGUMENTS 🦋

• adv — this is the target for the linkmode advertisement settings. so like, the thing you're writing into, bestie. point it at your advertisement settings and let it cook ✨
• val — the register value. yes it's a u32. yes that matters. no we're not changing it 🙈

👑 DESCRIPTION 👑

okay so what does this bad boy actually do? it's a function that translates the value of the following registers into the linkmode:

• IEEE 802.3-2018 45.2.3.10 "EEE control and capability 1" register (3.20)
• IEEE 802.3-2018 45.2.7.13 "EEE advertisement 1" register (7.60)
• IEEE 802.3-2018 45.2.7.14 "EEE link partner ability 1" register (7.61)

three registers, three chances to slay. it's giving translator energy — register value in, linkmode out, main character behaviour honestly 💖

ngl the register numbers and spec sections are the whole personality here, so keep 45.2.3.10, 3.20, 45.2.7.13, 7.60, 45.2.7.14, and 7.61 exactly as they are. iykyk 🌈
