💅 igc_power_down_phy_copper(9) 💅

okay so bestie, welcome to the Kernel API Manual — this one's a lil function page and honestly it's giving "quiet hero" energy. no drama, just vibes and power saving. let's get into it 🫶

✨ NAME ✨

igc_power_down_phy_copper — Power down copper PHY 💤

like literally that's the whole job. she naps so your machine doesn't burn battery. iconic.

🌸 SYNOPSIS 🌸

void igc_power_down_phy_copper (struct igc_hw *hw );

no return value, no mess, no cap. she just does the thing ✨

🎀 ARGUMENTS 🎀

  • hw — pointer to the HW structure 🌈 (yes bestie, THE hardware struct, the main character of the whole igc saga)

💖 DESCRIPTION 💖

okay so here's the tea 🍵 — this function powers down the PHY to save power when the interface is down and wake on lan is not enabled.

that's it. that's the paragraph. but think about it: interface is down, nobody's waking anything up over the network, so why keep the PHY awake burning watts for nobody? exactly. she rests. periodt 💅

ngl the two conditions matter here — interface down and WoL not enabled. if either one isn't true, this isn't the situation for this function. no shortcuts, bestie 🙈
