For SFF-8636 and SFF-8436 specifications, the driver exposes 256 bytes of EEPROM data for ethtool's get_module_eeprom() callback, resulting in "netlink error: Invalid argument" when an EEPROM read with an offset larger than 256 bytes is attempted. Changing the length enumerators to the _MAX_LEN variants exposes all 640 bytes of the EEPROM allowing upper pages 1, 2 and 3 to be read.
