💅 e1000_set_vco_speed — a Kernel API Manual moment

okay so first things first, bestie: this page lives in the Kernel API Manual (that's the manual name, we're folding it in here so it doesn't get lost 🫶). It's e1000_set_vco_speed(9) and it's short, sweet, and does exactly one iconic little thing. Let's get into it ✨

✨ SYNOPSIS ✨

s32 e1000_set_vco_speed (struct e1000_hw *hw );

That's the whole signature, no notes 💅

🎀 ARGUMENTS 🎀

  • hw — the struct that's holding all the variables our shared code needs to reach. Struct containing variables accessed by shared code. That's the vibe, that's the whole job of this parameter.

🌸 DESCRIPTION 🌸

so the actual tea here is: this function changes the VCO speed register 🎛️ and the reason is genuinely cute — it's to improve Bit Error Rate performance of SERDES 🌈 like, it's just out here making the signal less messy. no cap, that's it, that's the function 💖
