7000d321e8 Make smartpqi(4) behave better when running out of memory, by returning 
CAM_RESRC_UNAVAIL instead of CAM_REQUEUE_REQ.  This makes CAM delay a bit
before retrying, so that the retries actually get a chance to succeed.

1e66f787c8 martpqi(4): 
- Microsemi SCSI driver for PQI controllers.
- Found on newer model HP servers.
- Restrict to AMD64 only as per developer request.

The driver provides support for the new generation of PQI controllers
from Microsemi. This driver is the first SCSI driver to implement the PQI
queuing model and it will replace the aacraid driver for Adaptec Series 9
controllers.  HARDWARE Controllers supported by the driver include:

    HPE Gen10 Smart Array Controller Family
    OEM Controllers based on the Microsemi Chipset.
