1. Introduce module parameter perf_mode for only Aero/Sea
generation HBAs.
2. Update IOC page1 fields according to performance mode.
Below are the performance modes that can be
enabled with module parameter perf_mode.

Interrupt coale
Aero controllers supports balanced performance mode and driver enables
set of high iops and low latency reply queue only if,
- HBA is an AERO controller,
- MSIXs vector supported by the HBA is 128,
- Total CPU count in the system more than high iops queue count,
- Loaded driver with default ma
High iops queues are mapped to non-managed irqs.
Set affinity of non-managed irqs to local numa node.
Low latency queues are mapped to managed irq.
Driver reserves some reply queues (pci_alloc_irq_vectors_affinity and
.pre_vectors interface is used to meet the goal) for max iops and rest
of queues
Update driver version from 28.100.00.00 to 29.100.00.00
This is equivalent to Phase 10 OOB driver.

Driver will use round robin method for io submission in batches
within the high iops queues when in-flight ios on the target device
is more than 8.
If in-flight ios per SCSI device more than 8, driver will use
high iops queue else driver will use low latency reply queues.

Code refactor:
In the IO submission path _base_get_msix_index is called twice,
one while getting the smid; msix index is saved in msix_io filed
in scsiio tracker and anther while posting the request descriptor(RD).
now code refactor is done to determine msix index only while posting
the request de
Enable interrupt coalescing only on high iops queues when
high iops queues are enabled.
In ioc config page 1, offset 0x14 (ProductSpecific field)
is used to determine interrupt coalescing enabled/disabled on per
reply descriptor post queue group(8) basis.
If 31st bit is zero then interrupt coalesc
Code refactoring.
In function _base_get_msix_index add scmd as second
argument. This change is required for creating function
pointer in next patch, where we introduce new function to
get the msix index for high iops queues

This code refactoring introduces function pointers.
Host uses Request Descriptors of different types for posting an entry
onto a request queue. Based on controller type and capabilities,
host can also use atomic descriptors other than normal
descriptors.
Using function pointer will avoid if-else s
If the Aero HBA supports Atomic Request Descriptors, it sets the Atomic

In this patch series we are adding below two features for
