** Description changed: SRU Justification: [Impact] Recovery from DownPort Containment events fail and the NVMe endpoint is not accessible in some scenarios. [Fix] These are some of the DPC fixes which help in handling some of the failure cases of DownPort Containment events.

Disable the memory space of NVMe end point device 2. Issue IO to the device 3. Observe dmesg. dmesg shows that EDR event is generated, link is contained and NVMe device is recovered. 2.
