💅 NAME 💅

okay so bestie, welcome to ice_read_mac_reg_eth56g(9) — that's the page title, from the Kernel API Manual no less 👑 — and it does exactly one iconic thing: read a PHY port register. that's it. that's the whole vibe. ✨

int ice_read_mac_reg_eth56g (struct ice_hw *hw , u8 port , u16 offset ,
u32 *val );

like, look at her. five things, completely unbothered, absolutely serving 🫶

🌸 ARGUMENTS 🌸

  • hw — pointer to the HW struct 💖 (yes the struct is literally the main character here)
  • port — Port number to be read
  • offset — Offset from PHY port register base
  • val — Pointer to the value to read (out param) — she writes into this one, so keep her safe 🥺

🦋 RETURN 🦋

the vibe check on your return value:

  • 0 — success ✨ slay, you did it
  • EINVAL — invalid port number or resource type 💀 something you passed in was not it
  • other — failed to read from PHY 😭 not us getting zero bytes of useful info

💜 SEE ALSO 💜

fr fr that's a whole friend group 💀 do NOT try to read them all in one sitting, hydrate first 🍓

🌈 okay bestie that's the page!! it's from ./drivers/net/ethernet/intel/ice and dated October 2026 — so she's an icon from the future, we love that for her 👑✨ go read some registers, you're gonna eat 💅🫶
