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
h3cLIIPStreamSrcL4PortMax.
If both h3cLIIPStreamSrcL4PortMin and h3cLIIPStreamSrcL4PortMax
are at their default values, the port number is effectively unused.
If h3cLIIPStreamSrcL4PortMin is equal to
h3cLIIPStreamSrcL4PortMax, only one port number to be intercepted.
