Just in case if you require a PCAP and my (Snort) test.conf which I am
using for testing.

This is how I am running the PCAP

$ snort -r  xforward.pcap -c /etc/test.conf -l /tmp/log/

and this is what is getting logged, Where I cannot see the ExtraData.

$ u2spewfoo /tmp/log/snort.alert.log.1379870179
