igb_update_n...hecksum_i210(9)

🌸 NAME 🌸

okay so this is the Kernel API Manual page for igb_update_nvm_checksum_i210(9) — the header shortens it to igb_update_n...hecksum_i210(9) — and it's literally just here to Update EEPROM checksum. that's the whole name, bestie 💅.

✨ SYNOPSIS ✨

s32 igb_update_nvm_checksum_i210 (struct e1000_hw *hw );

🎀 ARGUMENTS 🎀

• hw — pointer to the HW structure 🫶

🦋 DESCRIPTION 🦋

okay so here's the vibe: this function updates the EEPROM checksum. it does that by reading/adding each word of the EEPROM up to the checksum. then it calculates the EEPROM checksum and writes that value to the EEPROM. next, it commits EEPROM data onto the Flash. that's the whole little routine, no cap ✨.
