## Detailed Description

GENEVE protocol header. (draft-ietf-nvo3-geneve-09) Contains: 2-bits version (must be 0). 6-bits option length in four byte multiples, not including the eight bytes of the fixed tunnel header. 1-bit control packet. 1-bit critical options in packet. 6-bits reserved 16-bits Protocol Type. The protocol data unit after the Geneve header following the EtherType convention. Ethernet itself is represented by the value 0x6558. 24-bits Virtual Network Identifier (VNI). Virtual network unique identified. 8-bits reserved bits (must be 0 on transmission and ignored on receipt). More-bits (optional) variable length options.
