[PATCH v2 07/13] mpt3sas: Handle NVMe PCIe device related events generated from firmware.

Suganath Prabu S
2017-07-14T13:24:19Z

* The controller firmware sends separate events for NVMe devices and
PCIe switches similar to existing SAS events.

* NVMe device detection, addition and removal are reported by the
firmware through PCIe Topology Change list events.

* The PCIe device state change events are sent when the firmware
detects any abnormal conditions with a NVMe device or switch.

* The enumeration event are sent when the firmware starts PCIe device
enumeration and stops.

* This patch has the code change to handle the events and add/remove
NVMe devices in driver's inventory.
