igc_validate...hecksum_i225(9)

💅 igc_validate_nvm_checksum_i225(9) — like, the Kernel API Manual, section 9 bestie ✨

okay so picture this: you're deep in the igc driver, section 9 of the Kernel API Manual, and you need to know if the EEPROM is behaving. That's literally this page. Welcome 🫶

✨ NAME ✨

igc_validate_nvm_checksum_i225 — validate that EEPROM checksum, queen. It's giving "is this thing even real" energy 🎀

---

🌸 SYNOPSIS 🌸

s32 igc_validate_nvm_checksum_i225 (struct igc_hw *hw );

---

🦋 ARGUMENTS 🦋

• hw — pointer to the HW structure 💖 that's it, that's the whole argument list, we love a low-maintenance icon

---

👑 DESCRIPTION 👑

So what does she actually do? She calculates the EEPROM checksum by reading and adding each word of the EEPROM — every single word, no skipping, no shortcuts, main character focus 💅 — and then she verifies that the sum of the EEPROM equals 0xBABA. That's the whole vibe check. If the math lands on 0xBABA, we slay. That's the number to remember, bestie: 0xBABA ✨
