qed_mcp_phy_sfp_read(9)

📦 version 7.3.1, in nixpkgs unstable

okay bestie, welcome to the qed_mcp_phy_sfp_read(9) page from the Kernel API Manual — yes, we're reading a whole sfp and it's giving tiny-transceiver main-character energy ✨🦋

💖 NAME 💖

qed_mcp_phy_sfp_read — Read from sfp.

🌈 SYNOPSIS 🌈

int qed_mcp_phy_sfp_read (struct qed_hwfn *p_hwfn , struct qed_ptt *p_ptt , u32 port , u32 addr , u32 offset , u32 len , u8 *p_buf );

🎀 ARGUMENTS 🎀

  • p_hwfn — HW device data. The hardware's whole vibe lives here 💅
  • p_ptt — PTT required for register access. It's the required pass for register access, no skipping.
  • port — transceiver port. Which port we're talking to, bestie.
  • addr — I2C address. The I2C address, exactly as it says.
  • offset — offset in sfp. The offset in sfp, periodt.
  • len — buffer length. How long the buffer is.
  • p_buf — buffer to read into. This is where the read data goes 🫶

🔥 RETURN 🔥

The official return line is: Int - 0 - Operation was successul.

So 0 is the yay outcome, and yes the manpage really spells it successul 😭💖 we are keeping that exact spelling because details are sacred.
