💅 ixgbe_write_i2c_byte_82599 — a Kernel API Manual moment

okay so bestie, welcome to the Kernel API Manual entry for ixgbe_write_i2c_byte_82599(9) — yes the whole title is a mouthful, she's giving "my full government name" energy and honestly? iconic. ✨

🌸 NAME 🌸

ixgbe_write_i2c_byte_82599 — Writes 8 bit word over I2C 🦋

✨ SYNOPSIS ✨

int ixgbe_write_i2c_byte_82599 (struct ixgbe_hw *hw , u8 byte_offset ,
u8 dev_addr , u8 data );

🎀 ARGUMENTS 🎀

  • hw — pointer to hardware structure. it's giving "here's my hardware, do something with it" 🫶
  • byte_offset — byte offset to write. literally telling you where in the byte-y situation we're writing 👑
  • dev_addr — address to write to. the destination, the main character of this operation 💅
  • data — value to write. the actual payload, the moment, the ~content~ 🌟

💖 DESCRIPTION 💖

Performs byte write operation to SFP module's EEPROM over I2C interface at a specified device address.

fr fr, that's the whole vibe: we're sliding a byte into the SFP module's EEPROM, over I2C, at whatever device address you handed over. no cap, that's it. 🧚

🔥 SEE ALSO 🔥

Kernel file ./drivers/net/ethernet/intel/ixgbe/ixgbe_82599.c — the mothership, the source of truth, the place where all of these live:

like, go read all 35 of them, i'll wait. actually no i won't, but you should. 😭

a lil note from me to you: every single one of those _82599 functions is a whole separate manpage bestie — this one's just the byte-writing girlie. don't mix her up with ixgbe_read_i2c_byte_82599(9), they're siblings and the family resemblance is real. 🙈

and that's the page!! 🍓 source/version wise we're looking at ./drivers/net/ethernet/intel/i... (yes it's literally truncated like that in the footer, that's not me being lazy, that's the vibe) and the date is October 2026. mwah. 💜🎀✨
