Use MPI2_IOCSTATUS_MASK when checking IOCStatus to mask off the log bit, and
make a few more things endian-safe.

rounddown2 tends to produce longer lines than the original code
and when the code has a high indentation level it was not really
advantageous to do the replacement.
This tries to strike a balance between readability using the macros
and flexibility of having the expressions, so not everything is
converted.
- Updated all files with 2015 Avago copyright, and updated LSI's copyright
dates.
- Changed all of the PCI device strings from LSI to Avago Technologies (LSI).
- Added a sysctl variable to control how StartStopUnit behavior works. User can
select to spin down disks based on if disk is SSD or HDD.
- Inquiry data is required to tell if a disk will support SSU at shutdown or
not. Due to the addition of mpssas_async, which gets Advanced Info but not
Inquiry data, the setting of supports_SSU was moved to the
mpssas_scsiio_complete function, which snoops for any Inquiry commands. And,
since disks are shutdown as a target and not a LUN, this process was
simplified by basing it on targets and not LUNs.
- Added a sysctl variable that sets the amount of time to retry after sending a
failed SATA ID command. This helps with some bad disks and large disks that
require a lot of time to spin up. Part of this change was to add a callout to
handle timeouts with the SATA ID command. The callout function is called
mpssas_ata_id_timeout(). (Fixes PR 191348)
- Changed the way resets work by allowing I/O to continue to devices that are
not currently under a reset condition. This uses devq's instead of simq's and
makes use of the MPSSAS_TARGET_INRESET flag. This change also adds a function
called mpssas_prepare_tm().
- Some changes were made to reduce code duplication when getting a SAS address
for a SATA disk.
- Fixed some formatting and whitespace.
- Bump version of mps driver to 9.255.01.00-fbsd

message synced to the changes in r283632, those changes are now backed out.
Another commit will be done that is exactly the same as r283632 except it will
have to correct commit message.

- Wrong integer type was specified.
- Wrong or missing "access" specifier. The "access" specifier
sometimes included the SYSCTL type, which it should not, except for
procedural SYSCTL nodes.
- Logical OR where binary OR was expected.
- Properly assert the "access" argument passed to all SYSCTL macros,
using the CTASSERT macro. This applies to both static- and dynamically
created SYSCTLs.
- Properly assert the the data type for both static and dynamic
SYSCTLs. In the case of static SYSCTLs we only assert that the data
pointed to by the SYSCTL data pointer has the correct size, hence
there is no easy way to assert types in the C language outside a
C-function.
- Rewrote some code which doesn't pass a constant "access" specifier
when creating dynamic SYSCTL nodes, which is now a requirement.
- Updated "EXAMPLES" section in SYSCTL manual page.

This is derived from the mps(4) driver, but it supports only the 12Gb
IT and IR hardware including the SAS 3004, SAS 3008 and SAS 3108.
Some notes about this driver:
o The 12Gb hardware can do "FastPath" I/O, and that capability is included in
this driver.
o WarpDrive functionality has been removed, since it isn't supported in
the 12Gb driver interface.
o The Scatter/Gather list handling code is significantly different between
the 6Gb and 12Gb hardware. The 12Gb boards support IEEE Scatter/Gather
lists.
Thanks to LSI for developing and testing this driver for FreeBSD.
