The protocols previous to Mobile IP in your decode tree may have
"eaten up" those bytes. For example, the ethernet dissector
may have decided that the last 4 bytes are trailer bytes.
When a protocol knows how long its payload should be (and not
all do), we try to make the payload tvbuff that size before
passing it to the next dissector.

I don't know what comes before Mobile IP in your trace...
do any of those protocols appear to limit the size of the
Mobile IP tvbuff?
