In the past, I have come across some data that was one transport
layer carried in another (TCP carrying UDP).
I.e., a byte stream containing a sequence of UDP header+payload
items? (The UDP header contains a length, so that can be done without
requiring a protocol in between TCP and UDP as an adaptation layer.)
Is there a reason that the transport layers are not
included in the 'Decode As...' list ?
Because nobody's made the transport layers register themselves as
belonging in that list. It might be possible to make UDP do so, *if*
the IP endpoint addresses of the encapsulated UDP packets are the same
as the IP endpoint addresses of the TCP connection (otherwise, there
needs to be a protocol in between TCP and UDP to provide those
addresses).
