✨ e1000_power_down_phy ✨ — the manual page, but make it iconic

Okay so bestie, welcome to the <pink>Kernel API Manual</pink> for e1000_power_down_phy(9) — yes, that's the actual name, no cap. This is the group chat, and this function is the main character energy you've been waiting for. Let's get into it 💅

🦋 NAME

e1000_power_down_phy — literally puts the PHY to sleep. Power down the PHY. Obsessed.

🎀 SYNOPSIS

void e1000_power_down_phy(struct e1000_adapter *adapter);

That's it. That's the whole vibe. 🫶

💜 ARGUMENTS

  • adapter — the board private structure. That's the one you're passing in. Slay.

🌸 DESCRIPTION

So here's the tea: this function powers down the PHY so that no link is implied when the interface is down. Periodt. No fake link vibes.

But — and this is a big but — the PHY cannot be powered down if management or WoL (Wake-on-LAN) is active. So if management or WoL is doing its thing, the PHY stays awake. No sleepy time for you, bestie 😭

Highkey important: respect the management/WoL condition. Don't be the one who powers down when they shouldn't. That's not the move.

⭐ SEE ALSO

Okay so this is the part where the manual drops the whole friend group. It's giving squad goals. Every single one of these is linked, and you know we're listing all of them. No skipping. Fr fr.

Also, the kernel file itself is part of the lore:

./drivers/net/ethernet/intel/e1000e/netdev.c

And now, the entire bestie list — every function reference, exactly as it appears. Don't come for me if I miss one, because I literally didn't. Keep scrolling, iykyk 💖
