[SCSI] fusion SAS support (mptsas driver) updates
Summary of Changes:
* splitting mpt_interrupt per Christophs suggestion
about a month ago
* rename ScsiCfgData to SpiCfgData structure,
then move all the raid related info into
new structure called RaidCfgData. This is
done because SAS supports RAID, as well as SPI,
so the raid stuff should be seperate.
* incorrect timeout calculation for cntdn
inside WaitForDoorbellAck and WaitForDoortbellInt
* add support for interpreting SAS Log Info
* Increase Event Log Size from 0xA to 0x32
* Fix bug in mptsas/mptfc/mptspi - when controller
has Initiator Mode Disabled, and only running in
TargetMode, the mptctl would panic when loading.
The fix is to return 0, instead of -ENODEV, in
SCSI LLD respective probe routines
* Fix bug in mptlan.c - driver will panic if
there is host reset, due to dev being set to
zero in mpt_lan_ioc_reset
* Fix's for SPI - Echo Buffer
* Several fix's in mptscsih_io_done - FCP Response
info, RESIDUAL_MISMATCH, Data Underrun, etc.
* Cleanup Error Handling - EH handlers,
mptscsih_flush_cmds, and zeroing out ScsiLookup
from mptscsih_qcmd
* Cleanup asyn event handling from
mptscsih -> mptscsih_event_process. Also
added support for SAS Persistent Table Full,
an asyn event
