The default TPID value is 0x8100.
The position of the TPID field in an Ethernet packet is the same as the position of the
protocol type field in a packet without VLAN Tag. Thus, to avoid confusion happening
when the switch forwards or receives a packet, you must not configure the following
protocol type values listed in Table 1-1 as the TPID value.
