This series patch include test cases for ipvs.
The test topology is who as below:

When /bin/sh is dash the line above results in an error
./ipvs.sh: 125: ./ipvs.sh: Syntax error: "(" unexpected (expecting "}")
Could you work on making the script free of bashisms.
Or, if that proves to be an exceisive burden, use #!/bin/bash
Thanks!
