✨ SYNOPSIS ✨

int get_phy_c22_id (struct mii_bus *bus , int addr , u32 *phy_id );

🦋 ARGUMENTS 🦋

  • bus — the target MII bus, aka the whole vibe location where the PHY lives.
  • addr — PHY address on the MII bus. It's the specific address, bestie.
  • phy_id — where to store the ID retrieved. She's the output pointer, periodt.

Okay so this function reads the 802.3 clause 22 PHY ID from the PHY at addr on the bus, and places it in phy_id. That's the whole main character move 💅.
