[tcpreplay] tcpreplay高级用法--使用tcpreplay-edit进行循环动态发包
tcpreplay-edit提供了可对包进行修改的高级用法：
--unique-ip
Modify IP addresses each loop iteration to generate unique flows. This option must appear in combination with the following options: loop. This option must not appear
in combination with any of the following options: seed, fuzz-seed. Ensure IPv4 and IPv6 packets will be unique for each --loop iteration. This is done in a way that will not alter packet CRC, and therefore will genrally not affect per‐
formance. This option will significantly increase the flows/sec over generated over multiple loop iterations. --unique-ip-loops=string
Number of times to loop before assigning new unique ip. This option may appear up to times. This option must appear in combination with the following options: unique-
ip. Number of --loop iterations before a new unique IP is assigned. Default is . Assumes both --loop and --unique-ip.
原包如下：
┬─[tong@T7:~/Data]─[:: AM]
╰─>$ sudo tcpreplay-edit -i replay-br0 -t baidu.pcap
收包如下：
[root@dpdk ~]# tcpdump -i eth1 -nn "tcp[tcpflags] & (tcp-syn) != 0 and tcp[tcpflags] & (tcp-ack) == 0"
::17.125017 IP 192.168.10.56. > 202.89.233.103.: Flags [S], seq , win , options [mss ,sackOK,TS val ecr ,nop,wscale ], length
::17.125093 IP 192.168.10.56. > 203.208.39.205.: Flags [S], seq , win , options [mss ,sackOK,TS val ecr ,nop,wscale ], length

使用，--uique-ip 参数可以在保证flow关系的前提下修改IP，修改策略是，源IP地址加一，目的IP地址减一
发包如下：
┬─[tong@T7:~/Data]─[:: AM]
╰─>$ sudo tcpreplay-edit -i replay-br0 -t --unique-ip -l3 baidu.pcap
收包如下：

再增加 --unique-ip-loops=3 参数，可以增加策略复杂性，效果就是，第2次loop和第3次loop的包，与第一次loop重复，例子如下：
