[V1] testpmd: add eeprom/module eeprom display

  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.

Hi David,

When sending a new version, can you please increase the verstion tag in the
title, V1 -> V2 -> ... -> vN

Also sending new patch as reply to previos one keep all versions in same email
thread and helps reviewers also people who later checks from archives for a feature.

For both above you can find more details in the contribution guide, please check
https://doc.dpdk.org/guides/contributing/patches.html#sending-patches


And there are a few errors below that this patch shouldn't be compiling
successfully, you can verify the build error from lab reports :)

This shouldn't compile because 'cmd_showmoduleeeprom' no more exists ...

There is a typo in the function name.

I guess this is copy/paste error 'len_eeprom' is not defined in this function.
There is one more occurance below.

Thank you so much, I will change to that format.

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.

Hi David,

The formatting is wrong in the patch and it is not detected as patch by
patchwork, can you please send the patch via "git send-eamil"?
