After changes from Olivier (applied few hours ago), Ethereal is able to decode PPP in GTP-U. Before it wasn't.
Thanks Olivier,
Michal

Speaking of PPP-over-GTP, do either of your changes address the
following question, asked last month?

Subject: [Ethereal-users] Decoding Problem of GTP-U frame for UMTS

Hello, everybody
I have a question about GTP frame decoding of ethereal.
I would like to know if ethereal can not decode PPP in GTP-U frame for
UMTS.
For example, PPP in GTP-U frame to be tested is as follows.
