- (r299263) Update MPI headers to version 42.
- (r299265) Several style changes and add copyrights for 2016.
- (r299266) Add support for the Broadcom (Avago/LSI) 9305 16 and 24 port HBA's.
- (r299267) No log bit in IOCStatus and endian-safe changes.

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

- (r299268) Change logging level for a debug string to use MPR_LOG instead of
MPR_INFO.

- (r299269) Fix possible use of invalid pointer.

It was possible to use an invalid pointer to get the target ID value. To fix
this, initialize a local Target ID variable to an invalid value and change that
variable to a valid value only if the pointer to the Target ID is not NULL.

- (r299270) No need to set the MPRSAS_SHUTDOWN flag because it's never used.
- (r299271) Use callout_reset_sbt() instead of callout_reset() if FreeBSD ver
is >= 1000029

- (r299272) done_ccb pointer can be used if it is NULL.

To prevent this, move check for done_ccb == NULL to before done_ccb is used in
mprsas_stop_unit_done().

- (r299274) Disks can go missing until a reboot is done in some cases.

This is due to the DevHandle not being released, which causes the Firmware to
not allow that disk to be re-added.

- (r299275) Bump version of mpr driver to 13.00.00.00-fbsd

MFC: r283661
- 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 mprssas_async, which gets Advanced Info but not
Inquiry data, the setting of supports_SSU was moved to the
mprsas_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
mprsas_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 mprsas_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 mpr driver to 9.255.01.00-fbsd
