The minimum value that the layer-4 destination port number in
the packet must have in order to match. This value must be
equal to or less than the value specified for this entry in
h3cLIIPStreamDestL4PortMax.
If both h3cLIIPStreamDestL4PortMin and h3cLIIPStreamDestL4PortMax
are at their default values, the port number is effectively unused.
If h3cLIIPStreamDestL4PortMin is equal to
h3cLIIPStreamDestL4PortMax, only one port number to be intercepted.
