(Step 2) Set MCK Link Down Time of hfcldd0 to 20. The new value for MCK Link Down Time

Figure Procedure to set a MCK Link Down Time value to the specified port
(Step 3) Set 10 as common MCK Link Down Time value to all other ports.
As for the parameters stored in FLASH-ROM, the latest value overwrites previous one.
Therefore, if a common value is configured, the value becomes effective for all ports including
each individual port, even if the port has previously configured values.
