Description:
The following captures show a captured DTN bundle:

Payload Header
Header Type: 1
Block Processing Control Flags: 0x08
.... ...0 = Replicate Block in Every Fragment: False
.... ..0. = Transmit Status if Block Can't be Processeed: False
.... .0.. = Delete Bundle if Block Can't be Processeed: False
.... 1... = Last Block: True

.0.. .... = Block Contains an EID-reference Field: False
Payload Length: 4
Comparing the time-stamp sequence number on bundles generated by our BPA,
which are a 64-bit number. The time-stamp sequence number generated is the
(hex) value 0x600000004,but It looks like the current DTN dissector is
expecting the sequence number to be no larger than 32 bits, this is a bug.
