> The counter management doesn't trigger 2 parallel events for the same

> When the port is stopped, the DevX event mechanism wrongly was
> destroyed what remained all the waiting pools in waiting state forever.

> As a result, the counters of the stuck pools were never updated again.

> Separate the DevX interrupt installation from the dev installation and
> remove the DevX interrupt unregistration\registration from the
> stop\start operations.

> Now, the DevX interrupt should be installed in probe and uninstalled in
