- * G bit: Bit 0 of the initial word is defined as the G (Group Based
- * Policy Extension) bit.
- *
- * I bit: where the I flag MUST be set to 1 for a valid
- * VXLAN Network ID (VNI).
- *
- * D bit: Bit 9 of the initial word is defined as the Don't Learn bit.
- * When set, this bit indicates that the egress VTEP MUST NOT learn the
- * source address of the encapsulated frame.
- *
- * E bit: Bit 10 of the initial word is defined as the bounce packet.
- * When set, this bit indicates that packet is bounced and must be
- * dropped.
- *
- * S bit: Bit 11 of the initial word is defined as the source policy
- * applied bit.
- *
- * A bit: Bit 12 of the initial word is defined as the A (Policy
- * Applied) bit. This bit is only defined as the A bit when the G bit
- * is set to 1.
- *
- * A = 1 indicates that the group policy has already been applied to
- * this packet. Policies MUST NOT be applied by devices when the A
- * bit is set.
- *
- * A = 0 indicates that the group policy has not been applied to this
- * packet. Group policies MUST be applied by devices when the A bit
- * is set to 0 and the destination Group has been determined.
- * Devices that apply the Group policy MUST set the A bit to 1 after
- * the policy has been applied.
- *
- * Group Policy ID: 16 bit identifier that indicates the source TSI
- * Group membership being encapsulated by VXLAN. Its value is source
- * class id.
- *
- * FOR INTERNAL USE ONLY
- * R bit: Bit 12 of the initial word is defined as the reflection bit
- * Set on packet rx checked on tx and dropped if set. this prevents
- * packets recieved on an iVXLAN tunnel being reflected back to
- * another.
