Bug Fixes/Enhancements:
=======================
Changes from version 102 to 110:

1) Defect LSIP200148189: 10/12-byte CDBs must be translated into 16-byte CDBs if the LBA exceeds 32 bits (multiple LDs on large physical arrays).
2) Defect LSIP200148733: Now setting IoFlags to the changed CDB length when converting CDBs either from 10/12=>16 or 16=>12.
3) Removed "noCDBconvert" registry switch that allowed disabled converting 16-byte CDBs to 10/12-byte CDBs.
4) Now setting ScsiStatus to SCSISTAT_QUEUE_FULL to address low performance on iMR with high queue depth.
5) Changed algorithm of setting the maximum busy-wait-count when exceed maximum number of IOs: default=10, registry setting = 1..Max/4.
6) Added check for invalid PD value in loading balancing setup code in fastpath map calculations code.
7) Defect LSIP200166574: BSOD: DRIVER_IRQL_NOT_LESS_OR_EQUAL on hibernation test in loop
8) Defect LSIP200148733) Potential data integrity issue with special I/O tool and reboots
9) Add PnP support per PR/IR (LSIP200172682, LSIP200169853, LSIP200148735)

Changes from version 100 to 102:

1) Fixed maxLD calculation, used in metrics.
2) Do not copy back uninitialized values the first time start metrics capture.
3) Moved metrics data capture to StartIO instead of BuildIO: must be synchronized.

Changes from version 90 to 100:

1) Defect 167740: avoid writing hotPlug bit more than once per firmware state, and clear when state is changed.
2) Allow registry setting for the BusyWaitCount, now defaulting to 10, and capped at 25% of the max request queue size.
3) Now initializing the collectTime used in collecting IO metrics, fixing bug when retrieving first sample.
4) Removed retrieval of LD_GET_LIST and PD_GET_LIST (still use PD_LIST_QUERY if supported).
5) Handle case of TB firmware not supporting MR_PD_QUERY_TYPE_EXPOSED_TO_HOST flag and process in completion routine.
6) Removed handling of some IOCTL completions and other requests for OS rescan to avoid excessive rescans.
7) Removed DriverStatistics code (IOCTL MR_DRIVER_IOCTL_MEGARAID_STATISTICS).
8) Check if firmware actually in fault state before test for resetRequired bit for 1068 controllers.
9) Don't write back the entire interrupt status value when either the response or change bits are set: only the change bit.
10) Remove incorrect handling of READ6 requests, which never happen in supported versions of Windows.
11) Removed all XP specific code, cleaned up some debug output code.

Changes from version 84 to 90:

1) Defect 143106: OCR does not reset controller on Falcon: using I20 registers instead of fusion ones.
2) Defect 153289: added pause after reading status register prior to reset avoids hardware check BSOD.
3) Avoid processing responses while in reset mode: check for flag after grab spin lock.
4) No longer assuming IEEE SGEs for Falcon/Tbolt controllers, use firmware setting instead.
5) Do not use more than 1 MSI queue when in hibernate/crashdump mode.
6) Changed the timeouts to 10 minutes for startup and 5 minutes for OCR.

Changes from version 78 to 84:

1) Defects 138881/145402: Must call StorPortBusy to wait for IO completions when request queue gets full, else get failed IOs.
2) Defects 139696/145324/136920/45055/45701: Overrun request queue with some sequential IO on multiple LDs, only for iMR.
3) Increase to 12 minutes the wait for firmware to become ready upon bootup or restart.
