ESXi - optical diagnostic information from VMNIC

I have been asked by one customer how to get optical diagnostic information from NIC which is Intel X540 10GbE Controller. NIC was identified by ESXi host as vmnic6 and more info about VNMIC can show command

esxcli network nic get -n vmnic6 

 esxcli network nic get -n vmnic6:

On ESXi host optics diagnostic is not implemented. I have found that ethtool in linux has the option -m which displays optic diagnostic information but ESXi ethtool do not support it. Monitoring Switch Port SFP/QSFP Hardware Information Using ethtool in Cumulus linux is described here.

During the research, I have found that linux -m option reads these diagnostic information from EEPROM.  On ESXi host, we can dump EEPROM by following esxcli command.

 esxcli network nic eeprom dump -l 1048560 -o 0 -n vmnic6  

Here is the EEPROM dump from Intel X520 NIC

Memory maps are described in specification SFF-8472 available on multiple places around the Internet.

Two 256 bytes memory maps are described in SFF-8472 Specification but the problem is how to locate these maps in EEPROM dump which has, in this particular case (Intel X520) 4,080 bytes.

I have prepared simple Perl script to convert hex numbers into ASCII characters and look what text is available in the dump. Perl script is here

 #!/usr/bin/perl  
 print "EEPROM view\n";  
 my $filename = 'eeprom.dump';  
 open(my $fh, '<', $filename) or die "Could not open file '$filename' $!";  
 $line = 0;  
 while (my $row = <$fh>) {  
  $line++;  
  chomp $row;  
  if ($line>2) {  
   print "$row\n";  
   $data_str = substr($row, 7, 48);  
   @data = split(" ",$data_str);  
   print "    ";  
   foreach $b_str (@data) {  
    $b = hex $b_str;  
    $char = chr($b);  
    if ( ($b>=32) and ($b<=126) ) {  
     print $char;  
     print " ";  
    } else {  
     print "- ";  
    }  
   }   
   print "\n";  
  }   
 }  

... and dump with ASCII translation is here ...

The most interesting part of the dump from text (ASCII) perspective is the part between 0550h and 05E0h.

There are adapter model and vendor name but it seems to me that it does not fit into the memory maps defined in the SFF-8472.  Therefore I do not know how to find optic (SFP) diagnostic values in EEPROM memory dump.

If you have any idea if I am in the right track and how to continue, please let me know.
