Snort and GTP encapsulation info

Hi all,

Again with an encapsulation question.

I am trying to understand how Snort manage GTP encapsulation, that I know that is supported. I already enable gtp in my 
config file by " config enable_gtp".

I run Snort with different pcaps that I have that include GTP and trying to see which info I obtained from Snort with a 
very silly rule to be sure that is triggerred.

My question is the following: Does somebody know where in the database is stored the TEID ( tunnel identifier ) of the 
packet that triggered the alert? . I have seen in Snort source code that it's parsed. But then I can not find it in the 
database.

Thanks
