🎀 SYNOPSIS 🎀

s32 igb_update_nvm_checksum (struct e1000_hw *hw );

---

🦋 ARGUMENTS 🦋

• hw — pointer to the HW structure

---

💅 DESCRIPTION 💅

okay so here’s the vibe: this function updates the EEPROM checksum by reading/adding each word of the EEPROM up to the checksum. Then it calculates the EEPROM checksum and writes the value to the EEPROM. That’s literally the whole glow-up. ✨
