In CTREQ, set `V' to 10, include both IPv4 and IPv6 addresses in
"Mobile Node's Previous IP Address" field, construct
IP Dest = PAR's IP (v4 _or_ v6) address provided in CTAR
IP Src = NAR's IP (v4 or v6) address.

Is the confusion in whether `V' bits also refer to
PAR and NAR addresses ? If so, we should clarify that they
refer to MN's IP addresses only, and that the router address
must be either IPv4 or IPv6 but not both.
