nvme: Allocate all MSI resources up front so that we can fall back to INTx if necessary.

nvme: Close hole where nvd(4) would not be notified of all nvme(4) instances if modules loaded during boot.

nvme: NVMe specification dictates 4-byte alignment for PRPs (not 8).

MFC r263277:

2014-05-07T17:00:39Z

nvme: Remove the software progress marker SET_FEATURE command during controller initialization. The spec says OS drivers should send this command after controller initialization completes successfully, but other NVMe OS drivers are not sending this command. This change will therefore reduce differences between the FreeBSD and other OS drivers.

For IDENTIFY passthrough commands to Chatham prototype controllers, copy the spoofed identify data into the user buffer rather than issuing the command to the controller, since Chatham IDENTIFY data is always spoofed. While here, fix a bug in the spoofed data for Chatham submission and completion queue entry sizes.

they occur. This prevents repeated notifications of the same event. Status of these events may be viewed at any time by viewing the SMART/Health Info Page using nvmecontrol, whether or not asynchronous events notifications for those events are enabled. This log page can be viewed using: nvmecontrol logpage -p 2 Future enhancements may re-enable these notifications on a periodic basis so that if the notified condition persists, it will continue to be logged.
