The mpt3sas_ctl_exit() should be called after communication with the
controller stops but currently it may cause false warnings about not
released memory. Fix this by letting mpt3sas_ctl_exit() handle misc driver
release per driver and release DMA in mpt3sas_ctl_release() per ioc.

pci_enable_pcie_error_reporting() enables the device to send ERR_*
Messages. Since commit f26e58bf6f ("PCI/AER: Enable error reporting when
AER is native"), the PCI core does this for all devices during enumeration,
so the driver doesn't need to do it itself.
Remove the redundant pci_enable_pcie_error_reporting() call from the
driver. Also remove the corresponding pci_disable_pcie_error_reporting()
from the driver .remove() path.
Note that this only controls ERR_* Messages from the device. An ERR_*
Message may cause the Root Port to generate an interrupt, depending on the
AER Root Error Command register managed by the AER service driver.

During system shutdown or reboot, mpt3sas will reset the firmware back to
ready state. However, the driver leaves running a watchdog work item
intended to keep the firmware in operational state. This causes a second,
unneeded reset on shutdown and moves the firmware back to operational
instead of in ready state as intended. And if the mpt3sas_fwfault_debug
module parameter is set, this extra reset also panics the system.
mpt3sas's scsih_shutdown needs to stop the watchdog before resetting the
firmware back to ready state.

While determining the SAS address of a drive, the driver checks whether the
handle number is less than the HBA phy count or not. If the handle number
is less than the HBA phy count then driver assumes that this handle belongs
to HBA and hence it assigns the HBA SAS address.
During IOC firmware downgrade operation, if the number of HBA phys is
reduced and the OS drive's device handle drops below the phy count while
determining the drive's SAS address, the driver ends up using the HBA's SAS
address. This leads to a mismatch of drive's SAS address and hence the
driver unregisters the OS drive and the system goes into read-only mode.
Update the IOC's num_phys to the HBA phy count provided by actual loaded
firmware.

Testing revealed a problem with how the reference tag was handled for
a WRITE_INSERT operation. The SCSI_PROT_REF_CHECK flag is not set when
the controller is asked to generate the protection information
(i.e. not DIX). And as a result the initial reference tag would not be
set in the WRITE_INSERT case.
Separate handling of the REF_CHECK and REF_INCREMENT flags to align
with both the DIX spec and the MPI implementation.

Signed-off-by: Martin K. Petersen <martin.petersen@oracle.com>
Currently, the mpt3sas driver sets the default queue depth based on the
physical interface of the attached device:
- SAS : 254
- SATA: 32
- NVMe: 128
The IOC firmware provides a recommended queue depth for each device through
SAS IO Unit Page1 for SAS/SATA and PCIe IO Unit Page 1 for NVMe devices.
If the host sets the queue depth greater than the firmware recommended
value, then the IOC places the I/Os above the recommended queue depth in an
internal pending queue. This consumes outstanding host-credit/resources,
thereby leading to potential starvation of other devices.
To avoid this, use the device depth recommended by the IOC firmware.

Enable the driver to work in non-IRQ mode, i.e. there will not be any MSI-X
vectors associated with queues dedicated to polling. The IOC hardware is
single submission queue and multiple reply queue. However, using the shared
host tagset support it is possible to simulate multiple hardware queues.
When poll_queues are enabled through the module parameter, the driver will
allocate extra reply queues without an MSI-X association. All I/O
completion on these queues will be done through the iopoll interface.

If a firmware fault occurs while scanning the devices during IOC
initialization then the driver issues the hard reset operation to recover
the IOC. However, the driver is not issuing a Port enable request
message as part of hard reset operation during IOC initialization. Due to
this, the driver will not receive get any device discovery-related events
and hence devices will not be accessible.
Teach the driver to gracefully handle firmware faults while scanning for
target devices during IOC initialization. Make the driver issue a port
enable request message as part of hard reset operation. This permits
receiving device discovery-related events from the firmware after the hard
reset operation completes.
