Table 11: Recommended path costs for RSTP based on the data rate.
a. Bridges that conform with IEEE 802.1D 1998 and only support 16-bit values for the path
costs should use the value 65,535 (FFFFH) for path costs when they are used in conjunction
with bridges that support 32-bit values for the path costs.
