i40e_validate_nvm_checksum(9)

💖 i40e_validate_nvm_checksum — Validate EEPROM checksum 💖

okay so bestie, welcome to the i40e_validate_nvm_checksum(9) page from the Kernel API Manual ✨ this one's a lil function but she's important, so let's get into it 🫶

---

🌸 NAME 🌸

i40e_validate_nvm_checksum — Validate EEPROM checksum 👑

---

🎀 SYNOPSIS 🎀

int i40e_validate_nvm_checksum (struct i40e_hw *hw , u16 *checksum );

---

🦋 ARGUMENTS 🦋

• hw — pointer to hardware structure 💅 like, the actual hardware vibes you're working with
• checksum — calculated checksum 🧮 this is where the calculated checksum ends up

---

✨ DESCRIPTION ✨

So what does she do? She performs checksum calculation and validates the NVM SW checksum 🔥 that's the whole gig, and she ate, no cap.

And here's the cute part: if the caller does not need the checksum, the value can be NULL 🙈 so you don't have to pass a real pointer if you're just here for the validation vibe check. lowkey convenient, fr fr.
