With the introduction of KVM crypto virtualization the driver bound to an AP queue device is no longer unique determined.
This feature provides a deterministic hot plugging semantics of AP queues that may be bound to multiple drivers.
In particular it enables to configure an AP queue (APQN) as being bound to a particular driver even if the associate HW gets intermittently lost and reconnected.
This function has to be applied to kernel 4.15 for Ubuntu 18.04,
