phylink_ethtool_set_wol(9)

📦 version 7.3.1, in nixpkgs unstable

okay so bestie, welcome to the Kernel API Manual page for phylink_ethtool_set_wol(9) — yes that whole mouthful is the name, and yes it's iconic. it's giving "set the wake on lan parameters" and honestly? that's exactly what it does. ✨

🌸 NAME 🌸

phylink_ethtool_set_wol — set wake on lan parameters. that's it, that's the whole vibe. 💅

🎀 SYNOPSIS 🎀

int phylink_ethtool_set_wol (struct phylink *pl , struct ethtool_wolinfo
*wol );

look at her go. two args, one int return, no cap. 🔥

🦋 ARGUMENTS 🦋

  • pl — a pointer to a struct phylink returned from phylink_create. like, the phylink you already made earlier. you know the one. 🫶
  • wol — a pointer to struct ethtool_wolinfo for the desired parameters. this is where you tell it exactly how you want your wake on lan situation to be set up. 🎀

💜 DESCRIPTION 💜

so basically: this sets the wake on lan parameters for the PHY attached to the phylink instance specified by pl. bestie. that's the whole job. 🌈

⚠️ no PHY attached? then it returns the EOPNOTSUPP error. not me getting rejected by a PHY that literally isn't there 😭

and the return vibes? returns zero on success or a negative errno code on failure. zero is the slay outcome, negative errno is the "we don't talk about it" outcome. 💀
