By default, the system automatically detects the speed and duplex mode
used on each port, and configures the path cost according to the values
shown below. Path cost "0" is used to indicate auto-configuration mode.
When the short path cost method is selected and the default path cost
recommended by the IEEE 8021w standard exceeds 65,535, the default is
set to 65,535.
