💅 genphy_c45_plca_get_status — a Kernel API Manual moment

okay so bestie, welcome to the Kernel API Manual ✨ this one's a function page, it lives in the kernel's genphy C45 fam, and no cap it's actually kind of a vibe. let's get into it 🫶

🌸 NAME 🌸

genphy_c45_plca_get_status — literally just get PLCA status from standard registers 💅 that's the whole job, she's a getter, she gets.

🦋 SYNOPSIS 🦋

int genphy_c45_plca_get_status (struct phy_device *phydev , struct
phy_plca_status *plca_st );

so she takes two args and hands you back an int, periodt 💖

🎀 ARGUMENTS 🎀

  • phydev — the target phy_device struct, aka the PHY you're clocking in at 🧚 this is your main character.
  • plca_st — the output structure where the PLCA status gets stored 🌸 like, she writes into this, that's the whole point.

🔥 DESCRIPTION 🔥

okay so here's the tea ☕ — if the PHY complies to the Open Alliance TC14 10BASE-T1S PLCA Management Registers specifications, then this function is the one you call to retrieve the current PLCA status information from the standard registers in MMD 31 ✨

that's the whole bit. no extra lore, she just reads MMD 31 and gives you the status. the way that's so clean of her honestly 👑

and yeah — that "if the PHY complies" is doing real work, bestie. if your PHY isn't down with the Open Alliance TC14 10BASE-T1S PLCA Management Registers spec, this isn't the function for you 🙈
