Generic UDP Encapsulation (GUE) is a general method for encapsulating packets of arbitrary IP protocols within a UDP tunnel. GUE provides an extensible header format with optional data. In this release, decap capability of GUE packets of variant 1 header format has been added to allow direct encapsulation of IPv4/IPV6 in UDP without the GUE header. The inner payload could be one of IPv4, IPv6, or MPLS.
