genphy_c45_plca_get_cfg(9)

📦 version 7.3.1, in nixpkgs unstable

💅 genphy_c45_plca_get_cfg(9) — like, the Kernel API Manual, bestie ✨

okay so welcome to the genphy_c45_plca_get_cfg page, straight out of the Kernel API Manual 🎀 this is the little function that goes and gets your PLCA config, and honestly? she's giving quiet competence. no cap.

🌸 NAME 🌸

genphy_c45_plca_get_cfg — get the PLCA configuration from the standard registers 🫶

✨ SYNOPSIS ✨

int genphy_c45_plca_get_cfg (struct phy_device *phydev , struct
       phy_plca_cfg *plca_cfg );

like, that's the whole vibe. two args, one int coming back at you 💖

🦋 ARGUMENTS 🦋

  • phydev — the target phy_device struct 👑 this is the PHY we're being nosy about.
  • plca_cfg — the output structure where the PLCA configuration gets stored 🍓 it's literally the lil basket you carry the answer home in.

💜 DESCRIPTION 💜

so here's the tea ☕ if the PHY complies to the Open Alliance TC14 10BASE-T1S PLCA Management Registers specifications, then you can use this function to retrieve the current PLCA configuration from the standard registers in MMD 31 ✨

that's it, that's the whole job. she reads the registers, she hands you the config, she slays 💅 no extra drama, no side quests.

⚠️ quick vibe check: this is conditional, bestie — the "if the PHY complies" part is doing so much work in that sentence. non-compliant PHY? don't come crying to her 😭
