Hi all,

When I run an RTT test just with the -d option, the test runs normally and I'm
getting results. When I add the --duration option, there are 2 unexpected
things happening:

1. The duration period doesn't take effect on the test, and
2. I'm getting 100% packet loss

Any ideas what the issue might be?
