MFC r318896: Fix several problems with mapping code in mpr(4).
-Add several comments describing what the mapping code is doing.
-Added a callout timer to improve check for missing devices when discovery has
completed so that missing counts are incremented correctly.
-Fix problems with missing counts not being saved to the HBA.
-Update man pages mps(4) and mpr(4) to include a description of the use
use_phy_num sysctl variable.
-Remove channel field in the mapping structure because it's not used.
-Improve logging by using mps_dprint or mpr_dprint instead of printf and adding
more logging where appropriate.
-Add check for a bad index before writing mapping entries to controller.
-The high missing count check in the mapping table was using the incorrect
initial value, which could lead to a bad result.
-The usage of the IN_USE flag for volume mapping was changed to be more
intuitive, and was not being used correctly.
-The check for a free DPM entry was changed, as this was completely wrong.
-Updates to the missing count for volumes were not being done correctly, so this
function was completely rewritten.
-_mapping_add_to_removal_table() was overly complicated and incorrectly used, so
this function was rewritten.
-Missing counts for all devices were not being incremented properly, so this
functionality was added.
-The search for space in the mapping table for missing enclosures was not
calculating the found space correctly due to not breaking out of a loop when
required, and the num_found variable was not being reset when needed.
-Retries when a device fails to get added due to a full mapping table were
removed because this is unneccessary.
-mps_mapping_is_reinit_required() and mpr_mapping_is_reinit_required() were
removed because they were not being used.
-Some functions were renamed to avoid confusion between Target IDs and SAS IDs.
-_mapping_check_update_ir_mt_idx() was removed because it was overly
complicating volume mapping.
-The setting of the maxtargets variable was changed to include max volumes.
-The setting of the initiator_id variable was changed to be the invalid target
ID after all targets, including volumes. Previously, this was set to the last
valid target ID.
-Don't exclude target IDs of RAID components or check for a reuse of a target ID
for RAID components.
-Some endienness was added.

r308217:
Add a fallback to the device mapper logic. We've seen systems in the field
that are apparently misconfigured by the manufacturer and cause the mapping
logic to fail. The fallback allows drive numbers to be assigned based on the
PHY number that they're attached to. Add sysctls and tunables to overrid
this new behavior, but they should be considered only necessary for debugging.

r312437:
Rework the debug print API. Event printing no longer gets special handling.
All of the printing from the tables file now has wrappers so that the
handling is cleaner and it's possible to print something out (say, during
development) without having to fight the global debug flags. This re-org
will also make it easier to have the tables be compiled out at build time
if desired.
Other than fixing some minor bugs, there are no user-visible changes from
this change

make a few more things endian-safe.

- 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.

have to correct commit message.

This is more consistent with the existing mps(4) behavior.
Reviewed by: Steve McConnell <stephen.mcconnell@avagotech.com>

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.
