The Ethernet II did not have that, but used the field as an EtherType. Because the ethernet MTU is defined as 1500 (0x05DC), the EtherType values at decimal 1536 (0x0600). Any value at or below decimal 1500 means it is the 802.3 ethernet using a length value.
EtherType - Wikipedia
EtherType is a two-octet field in an Ethernet frame. It is used to indicate which protocol is encapsulated in the payload of the frame and is used at the receiving end by the data link layer to determine how the payload is processed. The same field is also used to indicate the size of some Ethernet frames. EtherType … See more In modern implementations of Ethernet, the field within the Ethernet frame used to describe the EtherType can also be used to represent the size of the payload of the Ethernet Frame. Historically, depending on the type of Ethernet … See more 802.1Q VLAN tagging uses an 0x8100 EtherType value. The payload following includes a 16-bit tag control identifier (TCI) followed by an Ethernet frame beginning with a second (original) EtherType field for consumption by end stations.
