Please find some comments on ietf-softwire-encaps-safi, I hope these are 
useful:


     Tunnel Type (2 octets): It identifies the type of the tunneling
     technology being signaled. This document defines the following types:

       - L2TPv3: Tunnel Type = 1

L2TPv3 can be encapsulated in different ways over IP (e.g., directly
over IP proto 115, and over UDP). This document refers implicitly
(without mention) to L2TPv3 over IP (the only L2TPv3 mandatory
encapsulation from RFC3931), but does not explicitly clarify it. Could
this be disambiguated, e.g., by either: i. Renaming the Tunnel Type 1 to
"L2TPv3 over IP", or ii. Providing further L2TPv3 encap details (IP vs.
UDP, etc) in the Encapsulation sub-TLV for the L2TPv3 TLV Type?
