Please include the ethtool -m output so we can see what this decodes
to. I'd rather not have to keep on writing tools to parse hexdumps
back to binary and then using a custom tool based on ethtool to get
that information.
However, having the binary dump from ethtool -m emailed to me so it
can be added to my database of EEPROM contents for future testing
would be useful.
Thanks.
