📦 version 7.3.1, in nixpkgs unstable

💖 ixgbe_write_phy_reg_mdi 💖

okay so bestie, welcome to the ixgbe_write_phy_reg_mdi(9) page — that's the kernel API manual, and yes this lil function is the whole main character today. it Writes a value to specified PHY register without SWFW lock ✨ like, that's literally its whole job and it does it gorgeously.

🌸 SYNOPSIS 🌸

int ixgbe_write_phy_reg_mdi (struct ixgbe_hw *hw , u32 reg_addr , u32 device_type , u16 phy_data );

look at her. five things, all lined up, slaying. 🎀

👑 ARGUMENTS 👑

  • hw — pointer to hardware structure. it's giving "here's the hardware, do ur thing." 🫶
  • reg_addr — 32 bit PHY register to write. yes, 32 bit. write it down, don't be out here guessing. 💅
  • device_type — 5 bit device type. tiny but iconic. five bits of pure vibes. ⭐
  • phy_data — Data to write to the PHY register. the actual payload, the moment we've all been waiting for. 🔥
ngl the title says it all: no SWFW lock around here. that's the whole personality of this function, so don't come for her about it. 😭
