Well, there have been some debate about where to put the wedge layer w.r.t
some functionalities of the IP layer like fragmentation or IPSec. If it
turns that the wedge layer should be in the middle of the IP layer i.e. in
between the forwarding routing parta of IP and the endpoint part of IP like
fragment and IPSec, i would say that there is no difference between the both
cases, since we always would end with a new wedge in the middle of IP.
