ixgbe_write_...fer_bit_bang(9)

💅 NAME 💅

okay so bestie, welcome to the Kernel API Manual ✨ — this page is all about ixgbe_write_eeprom_buffer_bit_bang — she writes 16 bit word(s) to EEPROM 🎀 no cap, that's literally her whole job.

🌸 SYNOPSIS 🌸

int ixgbe_write_eeprom_buffer_bit_bang (struct ixgbe_hw *hw , u16 offset
, u16 words , u16 *data );

🦋 ARGUMENTS 🦋

• hw — pointer to hardware structure 💻 like, the actual hardware vibe check
• offset — offset within the EEPROM to be written to 📍 bestie, this is where in the EEPROM we're dropping our little gift
• words — number of word(s) 🔢 yes, plural, you can do more than one, icon behavior
• data — 16 bit word(s) to be written to the EEPROM 💾 the actual payload, the main character of this whole operation

✨ DESCRIPTION ✨

so here's the tea 🍵 — if ixgbe_eeprom_update_checksum is not called after this function, the EEPROM will most likely contain an invalid checksum 😭💀

⚠️ fr fr, don't skip the checksum step — that's giving "I forgot to hit save" energy and nobody wants that
