  Add module EEPROM/EEPROM dump command
   "show port <port_id> (module_eeprom|eeprom)"
Commands will dump the content of the EEPROM/module
EEPROM for the selected port.

Verified with some popular NICs, it can dump the same info as the Linux ethtool does.
This is supported in examples/ethtool as well.

Minor nitpick comments inlined.

Thanks,
