Ethernet II

• Ethernet II framing (also known as DIX Ethernet, named after DEC, Intel and Xerox, the major participants in its design[8])

• Ethernet II已成为事实标准，统一由新的 IEEE 802.3 standard维护

• In order to allow some frames using Ethernet II framing: 1. If EtherType values is greater than or equal to 1536(0x0600), the frame must be an Ethernet II frame; 2. If EtherType values is less than or equal to 1500(0x05DC), it must be an IEEE 802.3 frame; 3. Values between 1500 and 1536, exclusive, are undefined.
