ixgbe_updat...hecksum_X540(9)

💅 NAME 💅

ixgbe_update_eeprom_checksum_X540 — bestie, this one updates the EEPROM checksum and the flash ✨

Ok so real talk, we're in the Kernel API Manual today, and this function is lowkey the cleanup crew of the X540 EEPROM world. Let me tell you everything 🫶

---

🌸 SYNOPSIS 🌸

int ixgbe_update_eeprom_checksum_X540 (struct ixgbe_hw *hw );

---

🎀 ARGUMENTS 🎀

• hw — pointer to hardware structure. That's it. That's the whole argument list. She's a one-argument icon 👑

---

🦋 DESCRIPTION 🦋

Okay so picture this: you've just written the EEPROM to shadow RAM using the EEWR register (iykyk), and now somebody has to do the math 😭 And that somebody is the software, bestie.

After that EEWR write happens, software calculates the checksum, updates the EEPROM, and then tells the hardware to go update the flash. Literally the whole pipeline: calculate ✨ update ✨ instruct ✨. Periodt.

💀 friendly reminder that all of these got that (9) on the end because they live in the kernel API section — don't come for me, that's just how the manual rolls.
