ixgbe_write_eeprom_buffer_bit_bang_generic - Write EEPROM using bit-bang : pointer to hardware structure : offset within the EEPROM to write : number of words : 16 bit word(s) to write to EEPROM

Reads 16 bit word(s) from EEPROM through bit-bang method

s32 ixgbe_write_eeprom_generic	(	struct ixgbe_hw *	hw,
		u16	offset,
		u16	data
	)

ixgbe_write_eeprom_generic - Writes 16 bit value to EEPROM : pointer to hardware structure : offset within the EEPROM to be written to : 16 bit word to be written to the EEPROM

If ixgbe_eeprom_update_checksum is not called after this function, the EEPROM will most likely contain an invalid checksum.
