New revision: 279253
URL: https://svnweb.freebsd.org/changeset/base/279253

Log:
  - 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 20.00.00.00-fbsd
