      * Previously, the Single-Root I/O Virtualization (SR-IOV) Operator did not expire the acquired lease during the Operator's shutdown operation. This impacted a new instance of the Operator, because the new instance had to wait for the lease to expire before the new instance was operational. With this release, an update to the Operator shutdown logic ensures that the Operator expires the lease when the Operator is shutting down.

      Description of problem:

      After a controlled restart of the sriov operator (ex. rollout during an upgrade) it is taking 5+ mins to acquire the lease on startup.
