Yes and No. In general, we don't need to complete

This "issue" is not limited to missed packets only. This is applicable when
there is a flow in the kernel as well.

Yes. In addition, some packets may get sent to an OpenFlow controller.

Hi Samuel, my initial implementation was holding a reference to NBLs which were
indicated to user mode. However, there is an issue with that as in general not
