igb_power_d...copper_82575(9)

okay bestie, welcome to the igb_power_down_phy_copper_82575(9) page from the Kernel API Manual — niche kernel-core, but we're gonna make it make sense 💅

💖 NAME 💖

igb_power_down_phy_copper_82575 — Remove link during PHY power down. That's literally the whole name vibe.

✨ SYNOPSIS ✨

void igb_power_down_phy_copper_82575 (struct e1000_hw *hw );

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure. iconic pointer behavior, no notes.

🦋 DESCRIPTION 🦋

okay so here's the situation: in the case of a PHY power down to save power, or to turn off link during a driver unload, or wake on lan is not enabled, this function removes the link. that's it, that's the vibe 💖
