[tg] UDP issue

[Barbara Denny]

Hi,

For users who would like to send very large user
datagrams, try modifying MAX_PKT_SIZE in config.h.
The current maximum size is set to 8192. When
you add the unsigned long, which tg uses to
record a sequence number for udp, you get the 
results of the second run. All the bytes should 
be received by the end of the run.
