* VXLAN Header: This is an 8-byte field that has:
- *

* - Flags (8 bits): where the I flag MUST be set to 1 for a valid
* VXLAN Network ID (VNI). The other 7 bits (designated "R") are
* reserved fields and MUST be set to zero on transmission and
* ignored on receipt.

* - VXLAN Segment ID/VXLAN Network Identifier (VNI): this is a
* 24-bit value used to designate the individual VXLAN overlay
* network on which the communicating VMs are situated. VMs in
