An UNMAP command on a PI formatted device will leave the Logical Block
Application Tag and Logical Block Reference Tag as all F's (for those LBAs
that are unmapped). To avoid IO errors if those LBAs are subsequently read
before they are written with valid tag fields, the MPI SCSI IO requests
need to set the EEDPFlags element EEDP Escape Mode field, Bits [7:6]
appropriately. A value of 2 should be set to disable all PI checks if the
Logical Block Application Tag is 0xFFFF for PI types 1 and 2. A value
of 3 should be set to disable all PI checks if the Logical Block
Application Tag is 0xFFFF and the Logical Block Reference Tag is
0xFFFFFFFF for PI type 3.

No. of MSIX vectors supported = min (Total no. of CPU cores,
MSIX vectors supported by card)
when RDPQ is disabled "max_msix_vectors" module parameter which was
declared as global was set to '8' and hence if there are more than one card
in system among which if RDPQ disabled card is enumerated first then only 8
MSIX vectors was getting enabled for all the cards(including RDPQ enabled
card,which can support more than 8 MSIX vectors).
Used local variable instead of global variable ,if RDPQ is disabled this
local variable is set to '8' else it is set to "max_msix_vectors" (by
default this is set to -1, whose value can be set by user during driver
load time).So now regardless of whether RDPQ disabled card is enumerated
first or RDPQ enabled card is enumerated first , MSIX vectors enabled
depends on the cards capability.

Trivial non-functional changes for a couple annoying things:
1) Functions local to files are not declared static, which is
frustrating when reading the code because it's non-obvious at first
glance what's actually called from other files.
2) Set-but-unused variables abound, presumably to mask -Wunused-result
errors in the past. None of these are flagged today though (with one
exception noted below), so remove them.
Fixing (2) exposed the fact that we improperly ignore the return value
of scsi_device_reprobe() in _scsih_reprobe_lun(). Fixing the calling
code to deal with the potential error is non-trivial, so for now just
WARN().

We blindly trust the hardware to give us NUL-terminated strings, which
is a bad idea because it doesn't always do that. For example:
[ 481.184784] mpt3sas_cm0: enclosure level(0x0000), connector name( \x3)
In this case, connector_name is four spaces. We got lucky here because
the 2nd byte beyond our character array happens to be a NUL. Fix this by
explicitly writing '\0' to the end of the string to ensure we don't run
off the edge of the world in printk().

freed.

parameter "smp_affinity_enable" to 1/0. By default this feature is

Driver assumes HighPriority credit as part of Global credit. But,
Firmware treats HighPriority credit value and global cedits as two
different values. Changed host queue algorithm to treat global credits
and highPriority credits as two different values.

The problem is that select and depend don't interact because Kconfig doesn't
have a SAT solver, so depend picks up dependencies and select does onward
selects, but select doesn't pick up dependencies. To fix this, we need to add
the correct dependencies to the MPT2SAS option like this.

The mpt2sas driver was recently folded into mpt3sas to reduce code
duplication.
To avoid problems for people that only have CONFIG_SCSI_MPT2SAS in their
.config we introduce a dummy option that will select MPT3SAS if MPT2SAS
was previously enabled.
This is a temporary measure and we will deprecate this config option in
4.6.

Before enabling MPI2_SCSIIO_CONTROL_TLR_ON flag in MPI SCSI IO request
message, check whether TLR is enabled on the drive using
'sas_is_tlr_enabled' API.
Actually in the driver code, driver is using below API's
1. sas_enable_tlr() - to enable the TLR
2. sas_disable_tlr() - to disable the TLR
3. sas_is_tlr_enabled() - to check whether TLR is enabled or not.
but in scsih_qcmd() we have missed to use sas_is_tlr_enabled() API,
instead we checking for TLR bit from flag field of driver's 'struct
MPT3SAS_DEVIC' structure. which is corrected with this patch.
