These new commands are added between 'cmd_config_loopback_all' &
'cmd_config_loopback_specific' commands, please pay more attention where
to add new code.
Can you please add them just after 'cmd_config_speed_specific' to group
related functionality together?

This is summary info, lots of details already omitted, 'lanes'
information is not imported enough to list here, can you please drop
this change?
