igb_validate_nvm_checksum(9)

🎀 igb_validate_nvm_checksum(9) 🎀

okay so bestie, welcome to the Kernel API Manual — this one's about igb_validate_nvm_checksum, and honestly it's giving "tiny function, huge responsibility" energy 💅

---

✨ NAME ✨

igb_validate_nvm_checksum — Validate EEPROM checksum 🧚

---

✨ SYNOPSIS ✨

s32 igb_validate_nvm_checksum (struct e1000_hw *hw );

---

✨ ARGUMENTS ✨

• hw — pointer to the HW structure 💖 literally just a pointer to the hardware struct, that's it, that's the whole argument, slay

---

✨ DESCRIPTION ✨

so what this icon actually does 👑 it calculates the EEPROM checksum by reading and adding each word of the EEPROM, and then it verifies that the sum of the EEPROM is equal to 0xBABA.

that's the vibe check fr fr — read every word, add 'em all up, and if the total doesn't land on 0xBABA then something's off 🔥 no cap, that constant is the whole personality of this function.
