   Gateway-Initiated Dual-Stack lite (GI-DS-lite) is a variant of Dual-
   Stack lite (DS-lite) applicable to certain tunnel-based access
   architectures.  GI-DS-lite extends existing access tunnels beyond the
   access gateway to an IPv4-IPv4 NAT using softwires with an embedded
   context identifier that uniquely identifies the end-system the
   tunneled packets belong to.  The access gateway determines which
   portion of the traffic requires NAT using local policies and sends/
   receives this portion to/from this softwire.
