The value of tmnxHwName is the name of the component as assigned
by the system software itself and is suitable for use in CLI commands.
This may be a text name such as 'console' or a port ID such as '2/2'.
If there is no predefined name then a zero length string is returned.
Note that the value of tmnxHwName for two component entries will
be the same if the CLI does not distinguish between them, e.g. the
chassis slot-1 and the card in slot-1.
