ixgbe_write_eewr_X540(9)

🌸 NAME 🌸

okay bestie, welcome to the Kernel API Manual page for ixgbe_write_eewr_X540(9). The function is ixgbe_write_eewr_X540 — Write EEPROM word using EEWR. That's the whole vibe: it writes an EEPROM word with EEWR. 💖

✨ SYNOPSIS ✨

int ixgbe_write_eewr_X540 (struct ixgbe_hw *hw , u16 offset , u16 data
);

Like, yes, that's the exact signature — don't come for me about the spacing, it's iconic. 👑

🎀 ARGUMENTS 🎀

• hw — pointer to hardware structure. literally the hardware struct pointer.
• offset — offset of word in the EEPROM to write. It tells the function where in the EEPROM the word goes.
• data — word write to the EEPROM. This is the word being written.

🦋 DESCRIPTION 🦋

Write a 16 bit word to the EEPROM using the EEWR register. No cap, that's the whole move: 16 bits, EEPROM, EEWR register. Slay. ✨
