Wanted to know the use case where we only POP the SRH ?

4.16.1<https://tools.ietf.org/html/draft-ietf-spring-srv6-network-programming-04#section-4.16.1>.  PSP: Penultimate Segment Pop of the SRH

   The SRH processing of the End, End.X and End.T behaviors are

   modified: after the instruction "S14.  Update IPv6 DA with Segment

   List[Segments Left]" is executed, the following instructions must be

   executed as well:



   S14.1.   If (updated SL == 0) {

   S14.2.      Pop the SRH

   S14.3.   }
