📦 version 7.3.1, in nixpkgs unstable

💅 hey bestie, this is ice_phy_res_address_eth56g(9)

okay so you found the ice_phy_res_address_eth56g(9) page in the Kernel API Manual — welcome, grab a snack 🍓, because this one is genuinely a little math girlie: it's the function that calculates a PHY port register address for you ✨ no cap.

🎀 NAME 🎀

ice_phy_res_address_eth56g — calculate a PHY port register address. that's the whole job. she computes, you use. periodt 💅

✨ SYNOPSIS ✨

int ice_phy_res_address_eth56g (struct ice_hw *hw , u8 lane , enum
       eth56g_res_type res_type , u32 offset , u32 *addr );

look at her 👑 returns an int, takes a struct ice_hw *hw, a u8 lane, an enum eth56g_res_type res_type, a u32 offset, and a u32 *addr to drop the answer into. iconic signature tbh.

🦋 ARGUMENTS 🦋

  • hw — pointer to the HW struct. the hardware main-character herself 🫶
  • lane — lane number to be written. yes bestie, the lane. pick one 🌈
  • res_type — the resource type (register/memory). iykyk which one you need 💀
  • offset — offset from the PHY port register base. your little starting point on the map 🗺️
  • addr — the result address. this is where the answer gets handed to you 🎁

💖 RETURN 💖

  • 0 — success 🎉 slay, the address happened
  • EINVAL — invalid port number or resource type 😭 something you passed in was not it, and she is telling you so, respectfully

🌸 SEE ALSO 🌸

the source lives in the kernel file ./drivers/net/ethernet/intel/ice/ice_ptp_hw.c — go say hi 🧚

and okay. the friend group here is HUGE. like, biggest group chat in the kernel. everybody showed up, so let's give them all their moment 💜:

ngl bestie, that SEE ALSO list gave me a cardio workout 💀 but every single one of them is here, we don't skip anyone in this house 🫶

okay that's the whole page!! before you go — tiny cute sign-off: this gem ships out of ./drivers/net/ethernet/intel/ice, dated October 2026, and yes the page answers to ice_phy_res_address_eth56g(9). mwah, go calculate some addresses 💜✨
