Again, I'm confused.  Why would we bump the version to v2?  What is
different in V2 compared to V1?

It's highly unlikely that there will ever be a V2.  The only reason we
went from V0 to V1 is to allow for more than 8 MAC addresses.  Now the
entire EEPROM is filled with MAC addresses, and so we've reached the hard
limit of 31.  We would need to switch to a new EEPROM device in order to
handle more, and none of the other information in the EEPROM is used by
U-Boot.
