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.
