What is the value for the size of the 802.1ad tag as listed?

Explanation:
802.1ad (QinQ) adds a second VLAN tag to the Ethernet frame, and each tag is 4 bytes. The standard Ethernet frame maximum size is 1518 bytes including the 14-byte header and 4-byte CRC. With one VLAN tag, the maximum becomes 1522 bytes; with a second tag, it becomes 1526 bytes. So the value listed for the size of the 802.1ad tagged frame is 1526 bytes. The other sizes don’t match the standard frame size when two tags are present (they would only apply in other contexts like smaller payloads or non-standard MTUs).
