I see the tests failed because of one of the timers changing between the 2 commands running.
I am not sure what to do with this so the tests won't be flakey, if you have a suggestion, let me know.
I also wanted to run some commands to create interfaces before the tests start, but I am guessing it doesn't work, because of permissions (to run ip).
Should I just add a script that does that and call it with sudo in the Makefile?

I do not have time for cleaning this up. I am blindly accepting contributions for now. Will clean up in my weekend (sorry, not my business project).

sudo is OK.

Please rebase to last which has bridge covered somehow.

For the CI test cases, please us similar stuff like https://github.com/nispor/nispor/blob/base/src/lib/integ_tests/veth.rs#L26

To me this ctor::ctor is a hack and very hard to understand for new contributor. Please use panic::catch_unwind().

And next time, be cautious on introducing new dependency.

@qinqon I removed some of the fields you added in your last PR, as they broke the tests.
The commit with the changes is this one, if you have a suggestion on how to make the tests pass, let me know.
We can do a revert later, to get the functionality back.

@cathay4t No rush, but it is ready for review/merge
