💅 ethtool_adv_to_mii_adv_x(9) 💅

okay so bestie, we're in the Kernel API Manual today and this one is a tiny little helper function but she is important, so let's get into it 🎀

🌸 NAME 🌸

ethtool_adv_to_mii_adv_x — and honestly? the original page left the description totally blank here like it forgot to finish its sentence 😭 so there's literally nothing after the dash. No cap. We move on, the DESCRIPTION has the tea 🍓

✨ SYNOPSIS ✨

u32 ethtool_adv_to_mii_adv_x (u32 ethadv );

🦋 ARGUMENTS 🦋

  • ethadv — the ethtool advertisement settings 💖 like, the input. the vibe. the raw advertisement bits you're handing over.

👑 DESCRIPTION 👑

so what does she actually do? she's a small helper function — tiny but booked and busy ✨ — that translates ethtool advertisement settings into phy autonegotiation advertisements for the MII_CTRL1000 register, specifically when you're in 1000Base-X mode. periodt. that's the whole job, and she does it flawlessly 💅

lowkey iconic that such a little function is doing the linguistic translation between two whole advertisement dialects 🧚
