<paragraph>
IPv4 options in packets of this Flow.
The information is encoded in a set of bit fields. For
each valid IPv4 option type, there is a bit in this set.
The bit is set to 1 if any observed packet of this Flow
contains the corresponding IPv4 option type. Otherwise,
if no observed packet of this Flow contained the
respective IPv4 option type, the value of the
corresponding bit is 0.
</paragraph>
<paragraph>
The list of valid IPv4 options is maintained by IANA.
Note that for identifying an option not just the 5-bit
Option Number, but all 8 bits of the Option Type need to
match one of the IPv4 options specified at
http://www.iana.org/assignments/ip-parameters.
</paragraph>
<paragraph>
Options are mapped to bits according to their option numbers.
Option number X is mapped to bit X.
The mapping is illustrated by the figure below.

TCP control bits observed for packets of this Flow.
The information is encoded in a set of bit fields.
For each TCP control bit, there is a bit in this
set. A bit is set to 1 if any observed packet of this
Flow has the corresponding TCP control bit set to 1.
A value of 0 for a bit indicates that the corresponding
bit was not set in any of the observed packets
of this Flow.
