e94bb9b26e Fix a potential problem when mfi_get_log_state and only 
release a command if one was allocated.
Also release the command in mfi_shutdown.

c0b332d17a Instead of using scsi probes to do device discovery, use the firmware 
commands to grab the device listing.  This resolves issues using
multiple volumes, where each volume was actually internally pointing
to target 0.

330df1ac0d Fix a typo when getting the log_state and set the flags on the 
command to signify it is being polled and expecting data to be dma'd
from the card.

fb595e7a9b Cleanup dcmd firmware processing into a single function, mfi_dcmd_command 
to avoid duplication and mistakes when setting up firmware commands
for submission.

c3a252361a Fix missing \n and when there are no arg's that means just print out 
the description so we don't have to do any more queries.  Disable the
event query code until it figured out since but it is similar to the
AEN detail so we should be able to get that working.

741367d5a5 Add in a bunch of things to the mfi driver: 
- Linux ioctl support, with the other Linux changes MegaCli
	will run if you mount linprocfs & linsysfs then set
	sysctl compat.linux.osrelease=2.6.12 or similar.  This works
	on i386.  It should work on amd64 but not well tested yet.
	StoreLib may or may not work.  Remember to kldload mfi_linux.
      - Add in AEN (Async Event Notification) support so we can
	get messages from the firmware when something happens.
	Not all messages are in defined in event detail.  Use
	event_log to try to figure out what happened.
      - Try to implement something like SIGIO for StoreLib.  Since
	mrmonitor doesn't work right I can't fully test it.  StoreLib
	works best with the rh9 base.  In theory mrmonitor isn't
	needed due to native driver support of AEN :-)
Now we can configure and monitor the RAID better.

aab582690e Fix 64-bit DMA. The problem was an incorrect flag check. Thanks to Paul 
Saab for helping to track this down.  Fix a error with 32bit DMA size
calculation that seemed to be harmless.  Add a few micro-optimizations while
I'm here.

2e21a3ef7e Add a driver for the new LSI MegaRAID SAS controller family. The 'MFI' name 
is derived from the phrase 'MegaRAID Firmware Interface' used by LSI.  This
driver provides a block interface to logical disks on the card and a minimal
management device.  It is MPSAFE, INTR_FAST, and 64-bit capable.

Thanks to Dell for providing hardware to test with and IronPort for
sponsoring the work.
