, int regnum , u16 val );

🌸 ARGUMENTS 🌸

  • bus — a pointer to the mii_bus structure, and that structure is the one pointing at our driver private. iykyk, it's the little handshake that gets you to the right place. 🫶
  • addr — the address. that's it, that's the whole thing. 🎀

The source of truth lives in the kernel file ./drivers/net/ethernet/intel/ixgbe/ixgbe_phy.c — go say hi to it sometime. 🌈

And because the kernel doc crew loves a group chat, here's the entire bestie roster, every single one, in order:

fr fr, that's a lot of i2c friends. the kernel's phy code is one big group chat and everybody's typing at once 💀

okay that's the whole page, bestie — go forth and write that clause 45 register 🌟

And for the cute sign-off: this lil' entry comes from the source ./drivers/net/ethernet/intel/i... (the manpage truncated it, not me 🙈), dated October 2026 of the Kernel API Manual. mwah 💋🎀
