✨ ixgbe_read_i2c_eeprom_82598(9) ✨

okay so bestie, welcome to the Kernel API Manual 💅 — this one is ixgbe_read_i2c_eeprom_82598(9) and it is, like, the little function that goes and grabs you a byte from the SFP module's EEPROM. no cap. let's get into it 🎀

🌸 NAME 🌸

ixgbe_read_i2c_eeprom_82598 — reads an 8 bit word over the I2C interface. that's it, that's the whole vibe 🦋

✨ SYNOPSIS ✨

int ixgbe_read_i2c_eeprom_82598 (struct ixgbe_hw *hw , u8 byte_offset ,
       u8 *eeprom_data );

like literally that's the signature, copy it exactly bestie, don't @ me 🙈

💖 ARGUMENTS 💖

  • hw — pointer to your hardware structure. this is the main character, the whole context, everything runs through it 👑
  • byte_offset — the EEPROM byte offset you wanna read. so like, which byte. be specific, she's not a mind reader 💅
  • eeprom_data — the value that got read. this is the output pointer, the little gift bag you get handed at the end 🎀

🦋 DESCRIPTION 🦋

so what actually happens? this bad boy performs an 8 byte read operation to the SFP module's EEPROM, and it does it over the I2C interface. that's the tea. that's the function. no cap ☕✨

and these are all her sibling functions, her little 82598 friend group, and honestly? iconic lineup 🔥:

go read them all, iykyk 🫶

okay that's the whole page!! go forth and read those EEPROM bytes, you absolute legend 🌈⭐

and finally, the cute little sign-off from the footer bestie: this page comes from source ./drivers/net/ethernet/intel/i..., dated October 2026, and it's all about ixgbe_read_i2c_eeprom_82598(9). mwah, slay, periodt 💜🍓🧚
