One of their last inventions has been to pretend that IPv6 allows EH
insertion/deletion en-route, based on their reading of RFC8200. Based on
a curious interpretation of the text, they claim that each waypoint
(intermmediate router that received the packet because its address was
set as de Destination Address) can insert/remove EHs, and they claim
that that's not a violation of RFC8200.
However, the PSP behavour doesn't even fit in that fictional
interpretation of RFC8200.
What PSP does is that, given:
---- B ----- C
routers, when B realizes, after processing the SRH and setting the Dest
Addr to the last segment, SegmentsLeft==0, it removes the SRH.
This case is not even covered by their fictional interpretation of RFC8200.
router B receives a packet whose DA belongs to B
in the pseudo code router B sets the DA of the packet to C before
removing the SRH, this is only the description of the internal
processing that happens in the router
this does *NOT* mean that router B can remove an SRH in a received
packet in which the DA belongs to C
