As far as i understand from 3GPP TS 09.60 version 7.8.0 Release 1998
GTP adds a 20 byte header. After this header I would expect a full IP
packet.
To my opinion a seperate tool to replace the encapsulated packets with
unecapsulated packets would be the prefered solution.
This would allow all other sorts of tools to work nicely. E.g. ethereal.
