Sure, that LISP control plane packet is an IP packet. But, every message
that is going between CP and UP will be named and numbered in 3GPP specs,
and so said in my first mail that its probably a new interface specific to
LISP.

With any of the IETF protocols, PMIPv6/LISP/ILA, it can be argued that
these are IP packets. But, we should note that there is interworking
needed with the 3GPP authentication infrastructure, and the protocol
specific control plane. Note that these protocols are not doing MN
identity establishment. May be I could be wrong here on the assumptions
you have around LISP MN capabilities, but to me MN is a standard 3GPP UE
with no special capabilities such as MIPv6/LISP MN stack.
