> Down was requesting queue disables, but then exited immediately without
> waiting for the queues to actually disable. This could allow any function called
> after i40evf_down to run immediately, including i40evf_up, and causes a
> memory leak.
> 
> This issue has been fixed in a recent refactor of the reset code, but add a
> couple WARN_ONs in the slow path to help us recognize if we reintroduce
> this issue or if we missed any cases.
