πŸ’… e1000_power_down_phy_copper_ich8lan

okay so real talk, this page lives in the Kernel API Manual, section 9 β€” yes, that e1000_power...pper_ich8lan(9) header situation up top, that's her full government name πŸ’–. And bestie, she is niche, but she's iconic and she does exactly one job flawlessly.


🌸 NAME 🌸

e1000_power_down_phy_copper_ich8lan β€” remove the link during PHY power down ✨

Basically: when the PHY is going night-night, the link does not get to hang around being cute. It's gone. Periodt. πŸ’€


πŸŽ€ SYNOPSIS πŸŽ€

void e1000_power_down_phy_copper_ich8lan (struct e1000_hw *hw );

No return value, no drama, just vibes and a void. 🫢


πŸ¦‹ ARGUMENTS πŸ¦‹

  • hw β€” pointer to the HW structure πŸ’»βœ¨ (that's the hardware struct, the main character of this whole function, lowkey)

🌈 DESCRIPTION 🌈

So here's the tea πŸ“: there are a few situations where the link needs to go bye-bye β€”

  • when the PHY is being powered down to save power (energy conservation slay πŸ”₯),
  • when the link needs to be turned off during a driver unload,
  • or when wake on lan is not enabled.

In all those cases, this function removes the link. That's it, that's the whole gig. Not me describing a whole function in one sentence and it still eating πŸ’….

no cap, the source phrasing is "remove the link" β€” so the link is removed. Don't go reading extra behaviour into it, bestie, this is the entire documented deal πŸ™ˆ
