Hey Alex, Sorry for the delay in coming back to you.
Thanks for following up on this and submitting the patches you wrote. They fix the issue that I was seeing ( ports are now being freed properly ).

Is that what you did? If I ran the command one by one, it is fine. The thing is that in lib/dpif-netdev.c, we postpone (using userspace rcu) the close of the netdev. So, the refcnt will reach zero, and destruct will be called, just delayed... I'll add a logic to remove the requirement of rcu postpone the close of netdev and solve this issue.
