samples: pktgen: allow to specify destination IP range (CIDR)
Currently, kernel pktgen has the feature to specify destination
address range for sending packet. (e.g. pgset "dst_min/dst_max")
But on samples, each pktgen script doesn't have any option to achieve this.
This commit adds the feature to specify the destination address range with CIDR.
-d : ($DEST_IP) destination IP. CIDR (e.g. 198.18.0.0/15) is also allowed
