@kubernetes/sig-network-bugs can someone with IPVS familiarity look at the changes to the test cases here?

[m1093782566]

@smarterclayton

I just changed the UT from single test case(IPV4) to multiple test cases(IPV4 and IPV6).

tests := {IPV4, IPV6}
for i := range tests {
  TestFOO(tests[i]) // Original test code
}

I know the change seems large, but many changes are just indent.

Ok, thanks
